- This video was requested by a commenter...I don't remember who, but this video is for you! I went with the method of producing biodiesel, but you could also go with simple saponification (different procedure though).
The process is very slow and long. It is much easier to simply buy glycerol from the store. It would be much faster and much more pure than making it yourself.
Glycerine can be made from triglycerides in vegetable oils. Most bio-fats are stored as triglycerides which are made of 3 fatty acids and a glycerol backbone. This is the same method as making biodiesel from vegetable oil. where glycerine is normally considered a by-product.

how did it taste? ;)
Funny seeing you here
Cody'sLab Oh, hey Cody.
It should taste sweet
cody try this experiment with isopropyl alcohol and explain what happens something strange for sure, not sure if it made soap, fats, etc would make for an interesting video. Also you could use the glycerin for a deep eutectic solution for solar panels or what have you
should taste sweet, but I don't actually recommend tasting nitroglycerin.
The person who requested it is probably going to be revisiting the nitric and sulfuric acid video's soon...
Headshotted718 what happens?
Nitric acid and sulfuric acid and glycerine creates nitroglycerine :)
Headshotted718 :) if your talking about me then i have already made nitroglycerine in the past (like 10 years ago) but not using the sulphuric - nitric acid mix, i was using ammonium nitrate and sulphuric acid... i have made nitric acid in the past too but since potassium nitrate is hard to get here (and other nitrates even harder) i dont use it for making nitric acid in experiments where i can replace the nitric acid with other things...
Well, if you're the one who requesting the video, then yes, I would be referring to you, lol. And by the way, you can get glycerine at most stores, like CVS or any store like that. And that's not a bad idea, I never thought of that. But for nitric acid, it doesnt have to be potassium nitrate, just any nitrate salt. Would it have made a difference to make nitric acid using the ammonium nitrate? Theoretically, it would be equally as consumptive of the nitrate if you converted it to acid first.
Headshotted718
glycerine here is available in all drug stores for really low price like $0.5US for 100ml. theoretically yes ammonium nitrate can be used to make nitric acid as all other nitrates but its not that simple... in this case you have ammonia ion not rare metal ion so the procedure should be quite different and you need way better equipment and NH4NO3 is not that good to work with... we had one forum (x-inventions) back in 1998-2001 where we talked about this but it seems even the highly skilled and experienced chemists were not sure that it can be done at all... i was trying several different ways back then but all my experiments was fails... even if you get the procedure right i bet its way too difficult to obtain pure nitric acid, i bet that it will be less than 50% so...
i love to see chemists make all the ingredients for experiment thats why i was asking for the video :) imagine, you make your own glycerine, you concentrate your own sulfuric acid from car battery, you make your own nitric acid and you make nitroglycerine :) thats what i was doing and i bet thats what will keep peoples interested...
I've been watching these videos on a binge for at least a month now and this is the first one that makes me actually want to buy all the lab equipment and try
4 year later did you ever do it? Buy some glassware and start building an amateur lab?
@@K0ester no
The gelled biodiesel was most likely due to water in the methanol. To get decent yields with this, you need very dry methanol and oil. Separation is also quite fast without water contaminating the transesterification.
use copper sulphate instead of lye, use metho and boiled linseed oil, add oxalic acid and walla air drying flexable ceramic glue.
This was EXTREMELY helpful and very well put together. I use glycerin as a preservative. Thank You very much for all your hard work and dedication in making this!
Ohh I use it to make a Dynamite 😂
@@s.t.shobanbabu5729 nitroglycerin💀💀💀
Yo can u send me recipe?
@@pajakisiwego501 its sulfuric acid added to nitric acid to make a solution that's in a ratio of something like 55:45, and then this is added to glycerin and nitration occurs -----> nitroglycerin
How is this helpful other than the fact its interesting? Like other than amusement, what's the point? A liter bottle of 100% pure glycerine is like $10 at the grocery store in the cosmetics section, his yield was like 23ml... like.. how helpful is it really?
That's a really good chemistry video. Even though we can't see any spectra, the video with commentary tells the story correctly and I have no trouble believing that you have pure glycerol at the end. It's viscosity is low because you just took it off the heat.
Your final yield is absolutely clear, very nice man!
Great videos. You have opened up a whole new mysterious world for me. Thank you.
Thank you so much, u r a life saver. I'm thankful that many channels on youtube provide experimental chemistry content. However, your channel provides more details and discusses important topics by the preparation of common needed chemicals. Your channel helped me alot in improving my practical chemistry skills.
I'll tell all of friends about ur channel. Please keep up the good work.
Awesome video Nile. Next, you could try to synthezise Ethylene by dehydrating Ethanol using Aluminum Catalyst Medium. And then react Ethylene with Carbon Monoxide to form Carboxylic Acid.
IT WAS REALLY SATISFYING TO WATCH THE REMOVAL AND DISTILLING OF THE IMPURITIES AND THE METHANOL AT THE END....GREAT JOB.....THANK YOU FOR MAKING THIS VIDEO
GOOD JOB FINDING YOUR CAPS LOCK
This video is best for making me understand....
Well done....
Keep it up👍
Had to laugh, at 0:32. This came up in my recommended, after watching some biodiesel making vids.
And you basically say, (it's not what he says, yes I know): "I'm making biodiesel, but i'm keeping the stuff everyone throws away, and i'm throwing away the biodiesel."
I died for a bit there. Lol
3:23 they could be glycerin. I made soap and decided to get the glycerin out, to do this I added a NaCl solution and left it over night in a shed. I came back the next morning and there were a solid soap layer and a solution layer with base, NaCl and glycerin. The blobs were in the layer with the glycerin.
Keep up the good work
Oh okay… that was pretty simple and straight-forward.
fantastic video. clear and easy to understand.
still... 800ml vegetable oil ---> 24ml glycerine.... >_>
Haha yeah. Definitely not the most efficient process. Much cheaper and easier to buy. I got 500ml for 9$ at the local pharmacy. High quality and low water content.
Nile Red yeah decided to try to do the math for it, and I think even if you bought a gallon of vegetable oil at $6.30 (estimated tax included) you'd still only end up with a theoretical yield of like .114L --- 114 ml. And that's not including cost of the stuff you have to mix it with, and the time you put into it and all that fun stuff.
Still a really cool video though. Whenever i watch his videos I feel like I know the world a little more.
I am glad to know you enjoy them :)
@@NileRed If I may add, when using castor oil, highest yields were obtained by using 1.5% catalyst by weight, reacted for 60 minutes, and had a stir rate of 1000 rpm. I think your synthesis mainly lacked time.
Time was found to be the biggest factor in maximizing yield. The second part you probably lacked was good stirring. I didn't do the math but I think you also used a non ideal amount of catalyst.
Most of it is fatty acid
Fun Fact: The a lot of those impurities in the glycerol are called phytosterols, which are closely related to cholesterol. Phytosterols are estrogenic in nature and can effect testosterone levels in men. Which isn't surprising because sterols sound a lot like steroids, and are the feedstock for synthetic Testosterone, Cortisone, and a whole bunch of other hormones.
I feel like I've seen this exact video before.
Me too, here again
Same, it's so weird.
Is this guy having some kind of Deja-Vu?
next please nitrate the glycerol :)
+IamIUareU I honestly want to but the legality is a little sketchy. I know I have a mercury fulminate video, but still. Maybe I just won't include the actual quantities to keep people safe.
Then again, the recipe is very easy to find.
Nile Red
i understand :) i had website and youtube channel for how to make the essential chemicals that you need to produce all kind of explosives, but yet in the end i was explaining too much how to find and how to make them, i noticed that my visitors were mostly young kids so i felt the responsibility to shut down the website and to delete all the videos... i was just 11 years old when i started making high explosives and energetic materials but it was different time and different way of parenting back then... you should do all sorts of explosives only for educational purposes just dont put details of how it is made... show the process without any info...
That is very unfortunate. I also started very young working with explosives and chemicals and it was a good experience. But it was dangerous.
Explosives do scare me though, honestly :p.
Nile Red
making explosives and blowing small stuff up is addiction (at least it was for me), i started with 0.1g and ended up at 2.5kg in few years :) that last biggest one scared me allot and thats when i stopped making huge amounts and started more scientific research with high energetic materials... i feel really bad that we didnt have cameras back then :( i had to remade the videos for my website but never ever dared to make more than 10g at a time ever again :) i was mostly making AP and MEKP and tons of black powder...
I never made quantities that large, but I do wish there were video cameras. Would love to re-watch some of the stuff I did.
The gel that formed is actually soap.
surfactant technically
Nice synthesis, even though I would order it online. Glycerin can be used to make soluble starch, which is quite usefull for several experiments like the iodine clock and iodometry.
now vape it.
Add the funny pollen and/or addictive coffin nail extract and you have me on board
@@elijahaitaok8624 bro does it work?
@@elijahaitaok8624 Jesus christ how high are you
Is the glycerin from the video pure at the end? Could it be used for food purposes or in the pharmaceutical industry or does it still have to be distilled? I would like to produce glycerin with a purity of 99.5%. So the rest is water.
Brilliantly put together!
Thanks for another awesome and most informative experiment! However, pharmacy grade glycerol is so darn cheap to buy, so why make it. Of course, it's fascinating to see it being made, which is certainly no simple experiment.
SHTF, someday we may not have a pharmacy...
I remember performing the saponification of olive oil at school using a concentrated sodium hydroxide solution. The glycerol would separe from the mixture as well if you left the solution without stirring.
Also, wouldn't an acid catalysed transesterification be better since you'd avoid generating the saponification product?
Without the saponification, wouldn't it become an equilibrium reaction?
supersmashsam I want see milk rm stay mathord
Adding NaCl could help seperate the soap from the glycerin if wikipedia is correct
Thanks, i cant wait to add it to my acid collection! :)
Best In Presentation, Preparation ..👍
Great Job..
who could not have an interest in bio diesel in this day and age?
debbie green When placed side by side with petrodiesel, biodiesel can not even compete. It's way more expensive and at the same time, a much worse fuel. Less energy, harder to burn, more susceptible to water absorption. You literally get less, for more. Call me when you find a way to make one billion gallons of it, until then it's a joke.
Ilir Kumi I just spent $6000 on a 7.3 rebuild, due to fuel tank delamination from my truck sitting for 2 years! In addition to that I spent $1200 on tanks and $800 on installation. THAT'S A TOTAL OF $8000!
Biodiesel is BAD for older systems because it's high solvent properties disolve solids that can accumulate at the injectors.
...but for a NEW truck or NEW system like I have B20 is perfect *(temperature permitting) for preventing contaminants to build up in the first place! Also ULSD has shitty lubricity and biodiesel has EXCELLENT LUBRICITY! So I would gladly pay an extra 20-50 cents per gallon to PROTECT MY INVESTMENT so it will last another 20yrs.
*3:20 More advanced refining techniques have been developed to remove the components of the biodiesel that gells at higher temperatures making it a more reliable fuel. I have 2 tanks on my truck that aren't manifolded so in the winter, I will run B20 in one tank and #2 in the other. On mild days I'll be using the B20, on colder days I will be using #2.
@@Bloated_Tony_Danza
Just about summed it up nicely
@@Bloated_Tony_Danza You can add 3% acetone and its the best diesel you can have.

We made biofuel in one of my chemistry classes this semester, the smell was so damn bad. You only heated it for 30 minutes but we were told to do 50 minutes and the entire lab smelled of heated canola oil.
try add some used McD oils for more tasty aroma LOL
Slowly becoming my favourite channel on TH-cam...
Thanks for the vid. Q: Do the last steps about clearing up the color matter to the effectiveness/chemistry of the glycerol, or is it just contaminants?
Why does sodium hydroxide love Starbucks?
It's so basic.
Nice
The door is that way...
I'm kinda surprised you didn't make soap, being that this is a saponification reaction.
+SecularMentat Ill make soap eventually.
isnt it also edible....and sweet? ive seen some people drink the stuff
Glycerin yeah, it's a food additive. It's also in all vaporizers.
SecularMentat huh ....I kinda wanr some now XD
+mechnokie blood Yeah, just that the stuff you make in a lab should NEVER be eaten!!! Apart from that, YES.
Hi, would those ratios all be the same if you used ethanol instead of methanol to produce fatty acid ethyl esters and glycerin? And could you use acetic acid instead of HCl in this process? Also when you talk about washing biodiesel (FAME or FAEE) with water, is that just simply shaking the two around and removing separated soap contaminants? Thanks man, great vid!
Seeing as I do energy research and own diesel powered machinery, I would DEFINITELY be keeping the bio diesel!
make a video on how to make methanol (not becuse i can't get any)but becuse i want to know
I have done wood dry distillation. You get quite a few products. The primary product is water and tar and it smells.
Distill Alkohol, take the fort couple of drops.
@@louistournas120 wood distillation must be done using a copper pipe, which acts as a catalyst and you obtain methanol...

@@XDfunnyguy yes
Awesome video taking notes and this is my first experiment 🥼🥽🧪
Wow..this video was absolutely awesome
can i also use ethanol?
I think yes, esterification with ethanol is still favored compared with glycerol.
I have same question...I need it for biodiesel.I know that pure ethanol
damages engine 'couse pistons are made out of aluminium but i think
ethyl esters are not dangerous...
Isn't this the same stuff thats in vapes or something like that?
xGerbil I think so
xGerbil Yes
not always, most of "vape liquids" use propylene glycol, which differs from glycerine by one less hydroxyl group (propane-1,2-diol vs propane-1,2,3-triol)
AK47Sasg Somewhat Wrong. Most vape liquids use a mix of Vegetable Glycerin and Propylene Glycol. It can be completely one or the other sometimes though.
Kerbd noted. I wasn't totally sure, but i checked, and where i come from (central Europe) most liquid manufacturers use propylene glycol as a vector for nicotine. I'm not denying that other compositions are in use elsewhere. I'm glad to będzie proven otherwise :)
It was probably my comment you read. I asked you because I was frustrated there was no glycerine production video on youtube, and if you search "how to make glycerine" you get a bunch of homemade lip balm video.
I'm sorry I missed your effort until now, but I know your other subscribers enjoyed it as much as I just did. Thank you!
Thanks for the information. I make my own biodiesel and was wanting to do something with the glycerin other than compost it. I may try this but honestly seems extremely time and money consuming. Would be fun to at least do it once.
VAPE NAYSH Y'ALL V/\!
lol haha
\//\
Yayayya
now make it NITRO!
You don't even know what you are talking about
that does not make sense
Wow, so much effort to make such a small amount of Glycerol
Tried to do this but using ethanol instead and near oil smoking point it became like a gel and now I have it in my room and it looks like sourdough but smells fruity
If lab products are pure, why is it dangerous to ingest them?
The glassware usually has unseen leftover chemicals on it. Also, the chemicals are usually not food grade
So it's contaminated usually?
industrial/chemical standards are just not fit for consumption. basically consider food from your own lab as "fallen to the floor' except ... the floor has been in contact with all sorts of acids, toxic substances and so on. wouldnt eat that, would you? :D
if you want a minute risk to become blind taste it, :D he used methanol to wash glycerol.

"Some of the most common uses are food products and pharmaceuticals"
Ummmmm... ever heard of dynamite?
Dynamite is so old fashioned; there are much better compounds now.
However, nitroglycerin is still an essential heart medicine
/. Which compounds are better?
Cool video. I'd be interested in making it for shisha, and soap.
It does seem like a lot of work. And I'd have to figure out the various processing additives too. 🤔
i think that you can to get glicerol and fatty acids (not biodiesel) using sulfuric acid in tempertures around to 100°C... and a future can to uses the fatty acids..
Жаль, незнаю английского языка(((
That’s amazing. Thanks for sharing!
so is this the same process used for the glycerin in skincare products? Is it safe to put something that was mixed with methane on your body?
This was cool to watch ! Thanks
After you scoop the jell out of the beaker, isn't most of what you are boiling off recoverable methanol?
so much for vegetable glycerine being a natural product
+ImHereCuzImBored There are very few pure substances in nature. Essential oils, herbal medicines; etc. are all made using harmful chemicals. That being said, these chemists are professional, and don't let any of that stuff get into the product. Furthermore, the use of supercritical CO2 as a universal solvent is becoming cheaper and more widespread in industrial chemistry.
Thanks for the video, what about Propylene Glycol (PG) and Vegetable Glycerin (VG)?
Will you please make a corn glycerin video. I have lived on grains for 4years and I don't like using VG. I would be very grateful. Thank you for all the hard work you put in your videos. I know it is very hard work with all the crap you plan for. That doesn't even cover everything that doesn't go with great planning (The unforeseen crap). Plus cost and everything else. Peace
This was more complex then I anticipated and took a lot of equipment :). But I guess it takes what it takes.
Mix the methanol with a higher molecular weight alcohol (butanol can be used and is easily found) in a 3:2 methanol:HMW-alcohol; it really helps with mixing the methanol and the oil.
+NileRed I have a question about alternative route. Recently I tried making soap the "old way" where the water phase (that contains glycerol) and soap are separated by adding salt. But when I let it to settle down the glycerol in the water phase solidified, because it was pretty chill outside. So I filtered it out and washed. Do you think it might be pure enough?
I have no means of making a proper analysis though. The only thing I tried was finding the melting point, which was quite sharp. That can indicate some level of purity, but it is not an actual proof. I would like to know your opinion.
Thank you.
Can I use ethanol alcohol instead of ethanol؟ THANK YOU SO MUCH
Very well explained.
I was so hoping to see a vid about the chemistry of diesel because of the glycerol. That may be because I'm a farmer and grow oil making plants often in my fields :)
Hello NileRed, is it possible to make glycerine only from Vegetable oil using NaOH(as equation says, you should get soap and glycerin).And in future can you include, like molarity and those stuffs in recipies?
Since the NaOH is a catalyst, how would this work without it?
Would it require more heat? Risking polymerization of the oil? Or would it just be snails pace slow?
I have no idea what I just watched but it sure was interesting
Thanks a lot. a highly beneficial video
Wow. That was really complicated. This stuff should be worth a fortune if it's always this hard to produce! Surely there is a way to synthesize it as opposed to extracting it.
crude glycerol is a side product of making biodiesel, which is a major industry, so it's available in large excess and nearly worthless because of oversupply. usually when you do a process like this you would save the biofuel and discard the glycerol rather than the other way around.
Why is the color removed from the glycerin? I loved that dark amber color and it would be great for my products.
Good job!
Is there a way to recover a bit of glycerol from the saponification reaction? Would avoid the use of harmful chemical.
Can we use normal alcohol instead of methanol
i'm pretty sure you can use ethanol
You should have used the _glycerine_ song by _Bush_ in here. Apparently glycerine is _so_ awesome, they had to write a song about it.
Don't let the days go by
Idk why this channel has sucked me in but I'm hooked keep it up I won't to see some pure electrolyte powder get pulled that would be a interesting buy
You should be able to use sulfuric acid instead of HCl?
This should work with ethanol, right?
I want to use it for foods/medicine/skincare.
Don’t let the days go by
Very nice and interesting.
Nile Red: A quick remark I learned in my first chemistry lab back in UG - don't ever throw a magnetic bar into a flask (as in 1:50). It has the potential to break the glass (especially when the flask is staying on a magnetic stirrer) and/or spill chemicals. Always insert it slowly and carefully while maintaining the flask in an angle.
Keep up the good work!
Peleg Bar Sapir That never occurred to me. It also depends on how this walled the glass is and how big the stir bar is I guess.
This is soo interesting and go figure I HATED chemistry in high school. Now I have an interest in it for certain reasons....lol
Excellent video!
Too bad i don't have all the equipments to try it out.
your video are awesome, do you have any cool reaction to use this glycerol as a useful product? In current days there is this challenge of what to do with all glycerol that is produced as by product of biodiesel.
This helped me a bunch, just made me sad you didn't have a use for the bio diesel. Going to use this method to make my glycerin colorless before turning it into soaps. May use ethanol insteat
did you escape the mormons and embrace satan?
why do you need to reduce the pH to 1? if the goal is just to remove the base from the solution wouldn't a pH just below 7 be enough? or is the strong acidic pH required to reverse any saponification?
would this work with vinegar?
I'm more interested in obtaining fatty acids but this is interesting, I somehow thought it would be much simpler to separate reasonably clean glycerine.
Any book you recommend for this detailed process and how to do this on large scale???
Is that Chemdraw you're using for the reaction equations?
Awesome! Thanks!
Is this the same stuff they use in bongs/water pipes? Always wondered if it was just that simple!
The gunk from the reaction of triglycerides, methanol & sodium hydroxide. Was that soap forming and if so would you be able to get glycerol from acid transesterification?
thank you!
Nice video💕
@NileRed I believe you end up with technical grade glycerin, how would you go about refining it further?
I use the glycerol (and the biodiesel) in combination with potassium permanganate to light fires at home.
What preservatives can be use for hot sauce oil to avoid mold from growing in it
Gonna watch this before it gets demonetized
NileRed question: At 5:20 where you are adding the NaOH could you have used a burret and drip it in if you were concerned about over shooting the amount?
Of course
