"A brand new, never before opened bottle of...." 😂
An undergraduate student working close to me decided to evaporate off some diethyl ether by holding an open round bottom flask (RBF) over a Bunsen Burner. Inevitably the ether ignited. She was hand holding the RBF, which was overflowing flames onto her hands. She held it for a while, not knowing what to do, and then threw the flask resulting in a lab fire. Take care with ether!
How can someone be so stupid?
:( hope her hands were ok after this.
@@michaelhicks8603 She was OK, and it was great luck that nobody was using the chemical balances at the time. That was where the flask landed.
So basically her choices were to ETHER hold the flask or throw it.
@@jpvoodoo5522 It was a volatile situation.
I used to have a collumn with the glass beads in, I wasn't sure how much difference it made til I broke it and switched to a normal vigreux. Turns out they actually do make quite a difference! They're super easy to break when cleaning though.
Question? When I clean my flasks, crystallization dishes, test tubes ex. I usually use piranha solution, but how and what do you use to clean out your columns, safely?
@@MichaelLapore-lk9jz I usually use piranha too, though it depends what I've run through it. Sometimes I'll use various solvents that are suited to the contaminants before a final piranha wash to get stuff sparkling.
Is piranha solution one of those mixtures of acids? (I vaguely recall _aqua regia_ is something like hydrochloric and sulfuric acids, able to dissolve gold.)
I'm guessing piranha solution is something that completely evaporates though, yeah?
@@SeanCMonahan Mix of hydrochloric and sulfuric is the piranha solution, aqua regia is nitric and hydrochloric
@@jakesteampson7043 Piranha solution is sulfuric acid and concentrated hydrogen peroxide. Not HCL.
Pro tip: Store your diethyl ether in an aluminium bottle at room temperature. It will build up a bit of pressure and you'll loose a few microliters every time you open it, but that way you don't have to put it in a freezer/refrigerator and especially don't have to let it warm up to room temperature before using it (to avoid condensation. This is applicable to everything, if you don't let it warm up to RT before opening it, condensation will build up and your product will take up moisture). Of course except if you live somewhere with temperatures much above 30 °C... Then I would put it in a fridge, but only an EX certified one! Don't put flammable substances in non EX certified fridges... It can end badly... With a fridge getting blown through a wall and spreading the chemicals inside it everywhere... You really don't want that to happen...
If you're lucky with the climate and your lab AC and heating is bad, your ether boils in the summer and your DMSO freezes in the winter 😂
that's brilliant! thanks so much for the tip!
@@Milkex... iron is better, limits the buildup of explosive peroxide.
Add a rusty nail for good measure.
Those premixed two cycle chainsaw fuel containers are perfect and people who use them tend to treat them as disposable so easy to get for free and already marked with flammable liquids labels!
@@petevenuti7355 can you post a link to said article?
In Germany we apparently only get plastic bottles...
@@darnoc4470 I don't have an article , it's just something multiple teachers told me 30-40 years ago .. preferential oxidization of the iron.
It's actually something I intend to do an experiment with, since I've had this discussion with other people.
@@petevenuti7355 reactivity sequence of metals? something like that? been the same time since i was at school but seems to stick in my mind from somewhere.
Cyanoacrylate glue works pretty well to repair broken pestles. Mine broke similarly and glued it with CA glue it lasts many years before you have to re-glue it.
NileRed reference :D "Brand new, never before opened"
Everytime one of this guys videos appears on my youtube i get so excited.
Same! Even if it's a reaction I've seen or done a million times before, the way he presents it makes it worth watching over again!!!
Good to see people replacing that one chemist that we all loved.
Did I read that wrong?
@@tek4 I guess? Did someone finally go boom?
@@derchromebacher4366I don't think so, I think they are referring to Nile red, and that he hasn't been uploading much.
Nile makes cookies and shorts now -- he didn't even buy a Rotary vacuum with all that cash
Disappointing
Ya NR.
The glass bead fractional columns are AMAZING. They can be noisy but man they work well
A lot of people told me that they work well, maybe I should give them a shot in the next videos?
For a better yield, use the sieves the ethanol was stored over as the nucleation material for the dehydration step.
Zeolite beads nucleate even better than silica quartz. There's no need to separate the dust from the sieves. The drying power of the sieves would itself help drive the equilibrium forward. And you get back the ethanol that would've been lost to adsorbtion into the macro-scale porosity of the beads. (Only water can enter the pores in the zeolite crystal matrix itself, but you do lose some amount of any other material to the larger-scale porosity between different crystal grains.)
What do you think of this, will it also loose alcohol: Adding desiccants like calcium oxide (quicklime) to absorb water from the ethanol.
Calcium oxide is also cheap and easy to get and maybe good for a DIY process.
If you want to get 100% ethanol, you should minimise contact with air and store it under argon (better in Schlenk tube). When I tried to get absolute ethanol by triple azeotrope (benzene, water and ethanol), even doing inert distillation I got only 95% ethanol, because it is very hygroscopic
You did mess something up there. 95% can be achieved with good distillation only. I don't know what didn't work out, but something is off there.
EthOH is hygroscopic, but it is possible to get it virtually anhydrous.
@@jackmclane1826 I used 95% as a starting material, I needed abs. Ethanol to make Schiff base. In the end, I used MS 3A, and achieved 99.8% Ethanol
Couldn't you just dump a bunch of magnesium sulfate or calcium chloride into 95% ethanol?
@@Psychx_ Probably yes, but you need a lot of it. I have never done that. There might be a risk of dissolving some of that in the residual water, which then lingers as contamination of your ethanol. It is mostly used to absorb, what molecular sieves can't or would take very long.
Good distillation: >94%
Sieves: 99.x%
MgSO4/CaCl: 99.9x%
Why not just add some calcium metal pieces to it or calcium oxide? im pretty sure that should make it very dry you just have to distill with a baked apparatus to remove any calcium in it.
Kolumne frakcyjną polecam owijać kawałkiem koca a nie folią aluminiową. Folia sprawia że kolumna nie ma gradientu temperatur (za bardzo się nagrzewa na całej długości) - zwłaszcza te specyficzne „chemland’owe” z kuleczkami. Owinięcie kocem daje perfekcyjną separacje destylowanych frakcji.
Ja mam patent że obok kolumny stawiam mały wiatraczek i cały czas ją owiewam (z umiarem bo inaczej to się wszystko skropli)
Welcome to wonders of distillation. With something like 6 plates or so you never get close to 95% from 40% in a single go. The key is to adjust temperature to keep the flow not too high ie. column reflux ratio higher. Often it is quicker to make a couple faster distillations at higher flow rate than a single very high reflux rate distillation.
Distillation seems so simple in theory but when you look more closely into it, you quicky notice you always get a mixture with the unwanted components.
Maybe if you use Sodium Carbonate to seperate the water from the Ethanol and then distill the Ethanol after seperating.
But thats not really the same as distilling it if you first seperate it.
@@TjallieBrrr You probably mean potassium carbonate instead of sodium. It is one well known method to separate water and ethanol. Indeed, those are quite different methods than simple distillation.
Many other methods like extractive and azeotropic distillation are also possible and often used industrially.
@@hoggif Potassium Carbonate works better but Sodium Carbonate also works, ive tried it but never distilled it so i dont know if Sodium Carbonate is completely insoluble in Ethanol.
It also seems to be fairly dependent on temperature or else the Sodium Carbonate will crash out if too cold.
I tried it with Vodka and when its warm/hot it will seperate into 2 nice layers.
Just a small expiriment i did a couple years ago
@@TjallieBrrr That was interesting to find out. Everyone seems to use potassium salt due to very low solubility. I have to give that one a try some day. Sodium carbonate is dirt cheap and so readily available.
I checked up some data and at 30C it has solubility of 30mg/100g in 95% ethanol, about 1g/100g in 50% ethanol and about 2g/100g in 40% ethanol.
Slight solubility is probably not a problem because it will most likely be redistilled anyway.
@@hoggif yeah thats exactly what i was thinking.
I have no idea how i got the idea of doing it, i remember scouring the internet and couldnt find anything and at some point just tried it and found what i just reported to you.
It would make Ethanol purification st home much easier.
If you tried it let me know please
1:05 i love the NileRed inside joke you've put in :D
Ahh. Devil ether. It makes you behave like the village drunkard in some early Irish novel. Total loss of all basic motor skills. Blurred vision, no balance, numb tongue. The mind recoils in horror... unable to communicate with the spinal column... which is interesting because you can actually watch yourself behaving in this terrible way... but you can't control it.
Your comment is giving me Fear and Loathing flashbacks
I’m so happy TH-cam recommended your channel to me. You’ve got an excitement and sense of humor that I really like. 😊
Thank you, I studied Chemistry, but never worked with it, now I'm thinking about making my own garage lab, and your channel is a inspiration to me.
Thank you for posting this informative video. And I really like your sense of humor!
Nice, I like the idea and side content.
Unfortunately here in Germany it's illegal to concentrate ethanol that isn't denaturated, even if it's already taxed. So we have to use denaturated alcohol for things like this.
A few recommendations:
- Stonehard material can better be crushed in a plastic bag with a hammer. Don't forget to wear safety goggles when doing this!
Commercial boiling stones are still the best choice and not too expensive at all.
- Azeotropic ethanol can be dried with calcium oxide, molecular sieves can be used to keep it dry because anhydrous ethanol is hygroscopic. Never heat the dried solvent together with the used drying agent because it might give back the water. Anhydrous sodium sulfate is better suited as a drying agent than calcium chloride because CaCl2 forms adducts with many organic solvents. It should only be used in drying tubes or desiccators, not in the solvent itself.
- This way selfmade diethyl ether might also contain traces of highly toxic and carcinogenic diethyl sullfate. Avoid inhaling the fumes!
- Never store highly volatile and flammable substances in normal fridges or freezers, because they are not secured against explosions!
- Diethyl ether and other peroxide forming solvents have to be tested with acidified iodide starch solution every time before heated. Never rely solely on your stabilizer.
- Whereever possible replace diethyl ether by methyltertbutyl ether which is much less volatile and flammable and doesn't form any peroxides at all.
- Since conc. sulfuric acid in any form is banned for hobby chemists in the EU, anhydrous zinc chloride can be used here instead.
Could you explain how diethyl sulfate is made here?
Could you explain how diethyl sulfate is made here?

"Brand new, never before opened bottle of vodka" sounds familliar... I don't know why...
You know you're watching a real chemist when he uses the Lego ice cubes for his ice bath
Fantastic video mate thanks for sharing 😊
This is so informative!!! Fantastic video; I love this kind of content!🌻🌼🐝
ATF Agent: Sir, we've had complaints of explosions on your property.
Me: "improved pestle"
love the longer content bro!
subscribed! great video., i like your humble attitude and sense of humor and you have great camera angles and interesting topics
Excellent video. Reminds me of happy days in the uni organic chemistry lab.
_Brand new, never before opened_
was good to see someone performing this function, as I have been planning on using the function to make ethylene gas for conversion into polyethylene plastic polymer and do some testing to try and insert other atoms like sulfur into it for conductive polymers such as pedot (plan is still to make both N and P charge doped polymers for semiconductive traits so layered we could make things like solar cells that are transparent, experiment with various frequency responses and clear OLEDs and such :)
Cool projects!
this was a fun video, thank you for your time.
I loved the “I got tired of distilling, so I said ‘Frik it’”. I don’t blame you - it’s a chore
Thank you for taking us on the adventure.
Very suitable name for the channel considering content of this video :)
btw nice work, already subscribed and shared with few friends.
Thank you!
Hey! I've used beakers for my vodka many a times! Thank you!
"PonysaniG" LMAO.
Love the NileRed reference
"Brand new, never before used bottle of..."
LMFAO at your petty, vengeful determination 😂❤
6:46 lol 😂 Glas bubbles having a mental breakdown 😅 Very interesting seperating column! I prefer using the good old vigreux column 😊 Or if I really need insane seperation and time, yield and amount isn't a problem, a simple glasstube filled with small pieces of glass tube.
In many states in the USA, some liquor stores sell "Everclear," grain alcohol distilled to 190 proof, i.e. 95% ethanol by volume.
Huh. Thought I was the only person to use spite thermite. Absolutely sensible reaction to it crossing you.
Funny that you're Polish, because I remember reading about a Polish alcoholic drink that was commonly spiked with Ether
I realy am missing old NR butyour video stands on its own not just a replacement
I have some science whisky in a glass next to me right now. Subscribed!
One thing you need to understand with distillation of anything, be it volatile solvents like etoh or polymers like cannabinoids, is patience is key. And if you have low wattage, low surface area (compared to a wiper or falling film), restricted vapor flow like 24/40 joints, and low wattage… Well. You’re either going to have to be VERY patient, or be comfortable with sub-100ml quantities.
ahh the classic NileRed "brand new, unopened bottle of []"
love it :D
16:50 Beautiful hand movement 👌
2:52 "gato" 👍
Bro, awesome video as always! Could you perhaps show us how to distill sulfuric acid safely to concentrate it from battery acid ? It's unfindable in Europe in concentrated form, and it's literally one of the most useful reagents ever.
Thanks! I will definitely do a video about concentrating sulfuric acid sometime in the future, I also have to use only the non official sources of sulfuric acid and recently I came arcoss some proffesional drain cleaner which is dirt cheap and consists of pure sulfuric acid, maybe in your county you could get something similar :)
Saying "destill sulfuric acid" and "safely" in one sentence is kinda crazy already... you need a lab with a fumehood imo...
@@Amateur.Chemistry Could you maybe point me to where you find drain cleaner like this ? I'm sure there's a way, I can definitely clean the acid but concentrating it makes me anxious af because heat + sulfuric acid on your skin and you become carbon 😃
I get my drain cleaner from a local online store, I don’t even need to purify it because it is just clean 96% h2so4. Before discovering this method I distilled battery acid but it was a mix of pain and danger and I am still afraid of it
How's drain cleaner called?
i like drinking ether.
The tags on this video are poetry: "beautiful fire experiment"
I really don't know why all of you amateur chemists have to shake liquids every time they're in bottles. This shaking not only means that the oxygen in the air above the gas space of the liquid diffuses much faster into the liquid. The same also happens with the air humidity. Just as a small example. If you fill sodium-dried diethyl ether from one bottle into another bottle the humidity introduced during decanting is already sufficient to affect very sensitive Grignard reactions, sometimes to completely prevent the formation of the Grignard reagent. So if you have half-full bottles with a liquid that should be anhydrous, don't shake the thing, so as not to speed up the absorption of O2 and H2O. If you want to carry out chemical syntheses, you should get used to the right way of working from the start. This comment is by no means meant to be malicious. It is only intended to make it clear that the correct handling of chemicals is just as important as the entire synthesis route. Chemistry is a wonderful natural science. However, reliable results can only be achieved if you use the same correct working methods as the author of the paper.
1:09 BRAND NEW, NEVER BEFORE OPENED
Those prepartion skills xD bruh
AC: I will be making some diethyl ether from vodka.
Autocaption: You mean "diet for liver from vodka?"
Very interesting
1:30 It looks weird , just watching it bro. I feel ya. I mean, Im just curious about this subject after watching other things, And Ive always know ether existed and some of its uses trying to learn more about it has been a troublsome bother.. Thanks for the video. I leave a Like.
Seems like a lot of work for something u can buy at the store... cool science though!
I
lol how you voiced this video is legit how my lab is i feel ya XD
Try putting a good handful of table salt into the ice-water baths, it will significantly bring the liquid water temperature down, closer to the temperature of the ice. I imagine it would stay at a low temperature longer too.
Alternatively you could just put a very strong saltwater solution ( not supersaturated, keep adding salt until it stops dissolving) in a freezer for a few days. I found that a chest freezer works best.
This guy is hilarious
Get a pc cooling pump with reservoir and radiator and mount it on a small plate. Then you have a great setup for later distilling that does not need refilling ice all the time.
A Snyder column like this one is probably better at fractionating close-boiling components than a Vigreux column but they can be prone to flooding.
If you think one fractional distillation column is bad, try 3 on top each other with 3 outlets. Only the top needed water cooling, the middle was air cooled, and the lowest was short path.
I don't think that would fit in my fume hood...
@evilplaguedoctor5158 I didn't have anything particularly harmful running through it. But I did have the excess gas/vapor run outside through a bubbler first.

Fun video, had some good laughs. Put some CA glue on the Pestle and it will be fine.
personally i use a long column packed with glass, i only insulate the flask, not the column
from my exp you want the "drop speed" to be the same on output as well as on reflux. or have the reflux speed faster than the collect speed
also i go slow over hours cuz my column was like over a meter but the seperation was perfect, depending on the ethanol source, sometimes i just have a slow "normal" distillation to get the bulk of water out
Very nice video
Thanks!
As an step up before the Destillation, put the vodka in the freezer. That will freeze out some of the water and you'll start with a higher concentration
But it must be very low -20 -30° C
@@CUBETechie Only if you want to freeze the whole 40%alcohol/water mix at 23.somethingsomething °C.
The water freezes out way earlier and raises the %C2H5OH. Just like in Saltwater - the Water freezes out, leaving a cooler more dense/salt-saturated seawater behind
6:39 Do not insulate your distilling column, the whole point of all those steps is to condense water and drip it back into the flask. If the temperature is too high you will not fully get that effect.
I stopped using broken borosilicate glass as boiling chips as I found it scars the crap out of my RBF's.
With this project you need 2 bottles of vodca, one for the reaction and one for you
16:51 why didn't you use that 2 neck rbf before, instead of using the single neck one and removing the distillation column again and again to pour the vodka in?
"Brand new, never before opened bottle of vodka" 🤣
where i live, you can buy 195 proof (97.5%) wood grain alcohol without any kind of license. it is actually sold as a drink for some unholy reason. and it is literally just ethanol made from wood (usually pine trees) and then distilled down to 97.5% purity. its actually quite pure because it is meant for human consumption. i once drank a double shot of it straight and its the only time i've ever had a hangover in my life. a lot of chemists where i live will buy this alcohol and use it for experiments because it saves so much time and is WAY cheaper than "lab grade" distilled ethanol
this was one my first experiments is quite hard to get the balence right
1:21 "Two shots of vodka..."
Okay! After watching you termite the living shit out of that offending glass piece, I decided to follow and subscribe to you're channel!
I'm glad you didn't grind up morning glory seeds and soak them in the diethyl ether to create lysergic diethylamide.
Its that easy? Lol
9:38 "I don't see what I did wrong" Maybe you raised the temperature too high.
Yeah, my heating mantle makes the temperature seem lower than it actually is so that was probably why it didn’t work
In this case would sulfur trioxide work to dry the ethanol, producing the sulfuric acid needed for the next reaction?
I love how it's quickly turned to " BURN STUFF WITH THERMITE !!! "xD
90% using a massive fractionating column starting from vodka! I think this column should be returned to sender. I think the boiling flask was not big enough for this setup; more boiling material + more wattage of heat would have meant a better throughput, which would have meant you wouldn't need to insulate your column as well, and you would have collected much more in a small period of time.
Holy shit! That's a skyscraper fractional distillation apparatus!👀
I once carried a gallon jug of diethyl ether through the subway to transport to it's destination; scariest day of my life!
I love my ponysanig tv. It’s the best tv I’ve ever seen!
It would be interesting to convert acetone into isopropanol!
Is everclear not available where you're at? That way you don't have to worry about the first distillation.
When distilling alcohol in general, and ethanol in particular, monitor your temperatures and know your boiling points (watch for when the temperatures stall as comparing with lab pure boiling points are not reliable). In my setup fractioning between methanol, ethanol, water, and impurities stalled around 168F, 184F, and 202F, and nothing useful came over higher than that. The lowest stall is methanol that I save for camp fuel and other experiments (nitromethanol is not nitromethane, but still interesting), the middle stall is ethanol at around 70% At the high stall I was getting around 40% but mostly water (your experiment was here, so you pretty much moved the solution from one flask to the other. ...just watch Moonshiners. It's pretty much exactly the same process). Save each "stall" in a separate flask (Your commercial vodka should only have a speed bump if at all at the low-stall point, or you have a lawsuit to persue) and check periodically on the high-stall to see if it is still flammable. Stop when it doesn't light anymore. You can then re-distill the high-stall end with the same process as many times it takes or as long as you care, and add the mid-stalls to the first run until the high stall is just boiling water or the boiling stops above the high-stall but below boiling water. Re-distill the mids, and you should get between 80-90% (I got 95% on one run (mid of the mids), and seived that part to make a bit of homemade E85 gasoline)
Oh yeah, and the condenser needs to be COLD. The warmer it is the more water will come over.
God damn bubbles
How about extracting it & purifying from starter fluid?
5:43... at least no one can say you weren't concerned about intermediate yield!
How did you avoid the diethyl sulfate formation
Having done quite a few distillations of ethanol myself, this was pretty frustrating to watch. It should take no longer than an hour per run for an entire liter. Also, like someone else stated, even with good reflux, you won't be able to get all the way to your target in one go. So my suggestion is: jack the set temperature much higher and do two or three runs.
I use a little beaker as a shot glass.
this wizard is hilarious. and possibly educational, but i flunked chemistry 30 years ago
"Vodka is just some dilute ethanol"
Bro's never heard of everclear
190-proof alcohol is banned for sale in 17 US states... I can get gallon jugs of vodka at costco, but even specialty shops can't carry more than 151.

Sees density being measured with a graduated cylinder ** cries in analytical chemistry **
That type of fractioning column is easily flooded, which is what you did, thus making it rather ineffective and slowing down your distillation as well.
You need to go slower with it
In free societies, one may purchase 95% ethanol at a liquor store.
