yess
thats borderline date rape, no no.
NovemberBegin yes
NovemberBegin I replace it with deer estrus. Now that is rape !!!!
You should've made a little cup where insects can go in but not out, put a little 1-octen-3-ol in the bottom and left it outside for a day and then see if it's an effective attractant.
It needs to be airborne, so misted with something like CO2 through a airstone. He was one step away from getting really good results, oh well, we get bitten by bugs all the time so we know it works...
@@tjyoyo3 i love to torture bugs with electricity, cold andor hot water, fire, salt etc
Damn psychopath

I love how real you are--you always admit when you made a mistake, even if it's not visible or if it was a dumb mistake. I love scientists who make science seem more human, because at the end of the day, science is one of the most human things there is.
It's actually very standard for chemists to admit mistakes, but it's more in the sense of lab journals and so on. You have to record everything, even your mistakes which does lead to a good practice, but usually most chemist's don't talk about their work outside of their circles
@@MrPbhuh Every chemist knows that a journal in which you publish mistakes would be far more beneficial for the craft than all those 99%+ yields that are never reproducable.

Science doesn’t exist I would know I made it
Why do you feel disappointed man coz it's cheap to get online? . You made it yourself man, that's a big achievement in my honest opinion. Great video
yeah but he got a yield of 2%..... which isn't that great. at all.
+ 70€ for that one needed thing
organochem really likes to fuck with yields.
If he just bubbled CO2 through an airstone with this... he was literally SO close, the insects would have detected it in the air then.

Nile Red- the only Guy/Chemist on youtube who really pulls long-time project through. Respect for that dude! XD
NurdRage also does. He's trying to synthesize pyrimethamine. And chemplayer made piperonal from pepper.
yeah I know he isn't the only one :D I am just hyping him because I love his content
Cody also does this pretty well. His projects are most of the times very different though.
really he he is awsome thanks to him
Thanks! :)
The fact that Nile described an Aldol condensation without saying a damn thing about “nucleophilicitiy, partial positive, nucleophilic attack on the carbonyl, pka,” and “alpha carbon chemistry” is beautiful. That’s how you know someone is brilliant.
Wtf are all those words... 😆 I am taking HL IB chemistry... I should learn soon..
a lot of the explanations in organic chemistry textbooks overcomplicate things for no reason making people think "Organic chemistry is awful and just memorisation" when for a lot of reactions the logic is quite simple
@@vladys5238 makes me think that it's worded in specific ways to make things seem more difficult than it really is, so that less people go into this field 🤔
@@charl7508 i honestly think that it is because a lot of the teachers and people who make textbooks don't actually understand what is happening properly so they cling to set phrases and words . It's very sad
@@vladys5238 as a chemist i agree with your words. Too much terminology and too little enjoying the learning. Also had to do with the fact that schools are businesses sometimes they dont teach things well enough, dont care.
i live in Africa, think I'll sit this one out gents.

Codyslab: I'm not sure why my cameras moving on it's own...
I honestly didn't think this video would come. A lot of videos saying "I'm making this chemical for my production of 1-octen-3-ol." But I didn't know if it would ever happen.
haha it finally did. It was a long and painful adventure
Was it that difficult?
you must be new lol
Yeah, it took a while for that to come about. Didn’t help that his original plan was ruined by his acrolein polymerizing.
You are amazing and though I hated chemistry in high school, you remind me why people might actually like this crazy stuff. Keep up the great work!
Most people don't like science because they were taught it poorly, science sucks when it's just a bunch of giant words in a boring book and confusing diagrams with long, dry lectures. It generally tends to be a lot more fun in practice, chemistry basically lets you be like a chef only instead of making tasty foods you can make weird chemicals to play with and blow things up lol (safely of course)
@@GiraffeFlavoredCondoms its significantly more complex than you're making it seem. Chemistry is like knowing every single pokemon, thier moves learned at each level for each generation, when they evolve, egg moves, height, weight, foot print type, egg category etc etc. Chemistry is ludicrously difficult to learn at a usable level
It's really nice that you show and explain the reaction mechanisms. It really adds to the understanding about what's happening, rather than just "I pour some of this in, then this happens"
Damn, could've just extracted this from me. I can't seem to catch a break when it comes to bug bites
Take some supplements that contain safe forms of Sulphur, down in Florida we had well water which had Sulphur and if you drank enough of it the mosquitos would mostly leave you alone.
@@100GTAGUY hey, thanks for the advice! I'll actually give that a try when camping season rolls around!
And once again you showed me that organic chemistry is way above my current state of knowledge
proud of you. been working towards this for months
Thanks!
I love how he always explains it like we are going to do it. There isn’t really another way to properly explain it WITHOUT sounding like a tutorial, but I still find it amusing
I just took ochem 2 last semester and its so gratifying understanding the mechanism of the aldol reaction.
Props to nilered's stirrer, it has been carrying this channel on its back
Hi, and thanks for all the vids. I hated chem when I took it 40 years ago, but I love watching your projects (and seriously lusting after your lab glass).
This particular bid was timely because I just deployed a 40W UV lamp zapper about 4 weeks ago in an area saturated by hurricane Harvey floods. The lamp on its own is moderately effective. I looked at adding an octenol cartridge, but these are just ridiculously expensive. My further looking at some articles also made me skeptical than octenol without a sustained release CO2 source would provide much incremental effectiveness.
Based on my reading and local observation of insect behavior, I've just deployed a decidely low tech next step. It's a 500ml bottle 80% filled with a 1:1:1 mixture by vol of sugar, scrap sweet wine, and water with a tablespoon each of cornstarch, flour, and dry baking yeast. The bottle is placed adjacent to the zapper.
If this seems to increase the zapper rate, I might experiment next with adding octenol to the mixture.
My thought process is as follows: while female mosquitoes are attracted to the CO2/heat/octenol produced by mammals, both male and female mosquitoes are attracted to sweet liquids (nectars) for nutrition. While only the females bite, they only bite after they've bred. Hopefully attracting the breeding pair near the light will reduce the actual egg carrying female population. Secondly, fermenting yeast seems to be a very strong attractant for many flying insects. Third, it's just a hunch but I suspect octenol isn't the only alcohol compound that attracts. I've observed flying insects attracted to glasses of wine, wine that has degraded to vinegar, and to bottled fruit vinegars.
I'll try to post my results here. Meanwhile, if anyone finds a source for sub cosmetic/food grade octenol, please share. I can get a 40kg barrel from China, but a couple of liters ought to last my lifetime.
What are your results?
Just use mushrooms?

I actually had to draw the whole Aldol condensation mechanism on my organic II test yesterday. interesting to see it in use.
The way you said “incredible yield” always makes me laugh
angelic yield lmao
I have been anticipating this video for a long time! Thanks for pulling though!
No problem!
You channel is wayyyy underrated!
I was gunna say what u mean but I said that 4 years ago
Looks like got the attention he deserves!
I appreciate so much that you took the time to explain the mechanism of the reaction honestly, thank you, is cool to understand what's going on
3:10
“ooh” I think “I wonder what the mechanism for that is, I bet it would be cool.”
Spend ages googling
*”Now I’m going to break it down mechanistically”*
“Ah for fuck’s sake”
Boy,... This is EXACTLY what I needed.
The MPV reduction does not achieve incredible yields, but try to mantain all the reactants solved in the solution (you can try to continously adding the aluminium isopropoxide "solved") to the reaction mixture. If you maintain the products in the solution, you just have to displace the equilibria by distilling the corresponding ketone. You can also try with sec-butanol as a solvent, its higher boiling point may favor the reaction.
The recovery of aluminium can be also made by using a saturated aqueous solution of oxalic acid, where aluminium oxalate/hydroxyde precipitates out during the phase separation.
KEEP GOING!
One of the most skillful moving shots I've ever seen.
I thoroughly enjoyed watching the whole process (precursor videos too).
Feel a bit sorry for you and want to give you a big hug,.
Even if you didn't attract any bugs in the end, it was all worth while because of the great videos.
:)
Could you mix this with candles wax?
Calm down Satan
that would be a epic birthday present.
Yes
who hurt you
That may be a good idea, depending on how typical use it
Loved the video. You saying "the remaining XY is washed with a little bit of Toluene" is as soothing as Bob Ross saying "now we'll put a few happy little trees there"
OMG I have been waiting on the edge of my seat for this video!!! Im so happy !!!!
Thanks God!!! Finally the most expected video! What an amazing and loooong work-out! MANY CONGRATS
I've been marathon watching your videos ever since you replied to my comment today lol. Thanks for replying by the way
16:43 😂THE STIRRER IS POSSESSED 😱😱
Congrats. Been waiting for this.
I like that you put the reactions on cards, so I know when to fast forward
Currently I'm going into grade 12 and hoping to follow through with chemical engineering afterwards (some thanks to you for extra inspiration there!) I assume these videos are more of a chemists hobby but what do you do for work? Keep up the awesome videos I'm sure you've inspired more kids like me!
@VoDx GT Currently in ~3rd year materials engineering as opposed to chemical. Taking my sweet time with my degree. No clue where I will end up career wise post-degree but I love thermodynamics and ceramic materials so something in that field I assume.
@@twisty093 that's cool, is ben dover your real name?
As a 4th year chemical engineering student, I took an ochem class in second year and never used it again... 😂
That moment when you look for the carbon in the Aldol Reaction and suddenly you remember.... but i had a few beers after work in my defense!
At last!!! I have been waiting for it!
That adapter is so clever!! Good video. :)
He mentioned making the metal smelling 1 octen 3 one in this video, about 3 years before he made a video on it. That’s kinda wild.
I want to spread a ton of this in my brothers yard when he throws a party
calm down satan
go on satan
finally. been waiting forever for this!
Your videos always help me fall asleep. I adore your voice and the interesting content behind it. Be safe 💜

“In my next video, we will make a chemical that attracts air horns and people who still aren’t over firefly being canceled.”
YES it's finally there :D looked forward to it
It's channels like these that made me enjoy chemistry and physics in school. Keep it up 👍
Hey Red, I got an idea for a video I'd enjoy seeing.
I recently read that _n-halosaccharins_ can act as convenient substitutes for n-halosuccinimdes in some reactions.
From what I've read I think they could potentially be quite useful to us hobbyists due to their versatility, ease of preparation and favourable safety profile.
I'd love seeing you try to replace N(X)S with the corresponding halosaccarin in some halogenation reaction.
I mean if its safe next to a current, slap that stuff on a bug zapper 😂
Very interesting. Keep em posted buddy
Thanks for showing the mechanism!
Wow that smell of metal on my fingers... That is really interesting. Talk more about that soon. :D

I actually already have one. I just dont have space for it!
Damn that's too bad lol.
+KakashiBallZ Too bad? He owns one! I would take one, but I don't have the space either.
+KakashiBallZ or the money
+Cole Ramsey too bad he doesn't have space...
Thats quality. Great job👌🙏
its so cool to see reactions we learn in school actually being used!
Don't you think that using column chromatography would be better to fractionate reaction mixtures than vacuum distillation? Btw nice channel, a lot of chemistry knowledge is coming from your videos 😉
I wish I showed up to chemistry so I could know what he's talking about. Still interesting tho
This is the stuff that comes with bug zappers, there are little fabric tabs that come with it, soaked in octenol, that supposedly attract bugs to the zapper.
i love how he allways says about following by a very exact number
This would be perfect to wipe on my enemies clothes during the summer.
What were the reasons that 1-octen-3-ol was believed to be an attractant of biting insects before the research showed that there was no major difference between traps baited with it and traps not baited with it?
Well form what I understand it's the same sent humans give of that attracts insects/mosquitto's so, even though they do the same the point was attracting them with a scent that they follow naurally, also, the report says that it would be a lot more potent if you combined both the trap and the 1 octen 3 ol together
When bubbled with CO2 it becomes misted/airborne, making it a airborne scent for those pesky bugs to find. much better then just coating a trap with it.
@NileRed, insects can be attracted or repelled by semiochemicals based on its potency / concentration. Good luck on your continued experiments. It was a pleasure to watch your video. Thank you.
No matter what!! nile never gives up on a project....he works through it and gets results whether it's a fail or success he learns from it and also makes us learn tooo....kudos💕🙌🏻🙌🏻
I'm a moron 😅 but I still enjoy watching and trying to understand the reactions taking place.
Same lol
Woe to company who doesn't hire you
best camera sweep to show a setup I've ever seen. and sloppily much product. lol . love the humor
Are you a teacher/ professor? Your passion bleeds into your teaching methods and it’s very engaging. I watch these for joy, and I wasn’t good at science at all. It’s the passion that keeps me watching.
for around $80, I found 1000 grams of 2-heptanone on sigma aldrich. It was 98% pure
You've gotta be attached to an institution or a company to order stuff from them and I don't know if he's allowed to order reactants for private use through his workplace... I'd reckon the answer is no.

Hm
Is. That an actual loophole? Not that anyone can do of course

Thanks for inspiring me to review my organic chemistry, I'm taking up chemical engineering and I've already forgotten everything just 2 terms after my last organic chemistry subject. I seriously had to pick up my book and re-read about aldol reaction mechanisms. The alpha-carbon of one ketone attaches itself to the carbonyl group of the other carbon in basic conditions
Love it. appreciate even the less successful vids. Thanks.
5:15 your intermediate is a beta-hydroxyketone in the diagram, but you said it's an aldehyde, or am I missing something?
I was confused about this too.
That is correct, he made a mistake there.

Your channel is the first channel I subscribed on youtube and this comment is my first comment on TH-cam too. You are doing a nice (and in some cases very dangerous) Chemistry. Keep it up. As a suggestion, try some coordination chemistry. Coordination compounds have nice colors.
In highschool they teached us how to inject poison into nuts to kill squirls
JQuery I didn't know they taught chemistry to downies
Excited for the NileGreen on this one
I dont understand most of the things. But still enjoy watching it. Thanks.
Just what I was looking for. There are entirely not enough biting insects around for my taste. Great recipe, thank you.
Imagine concentrating this and putting in ur friends sunscreen or soap
May I recommend a series for your channel? How about basic Organic Chemistry, and General chemistry reactions? I always have trouble with new reactions in my university labs. Some of your videos like the extraction of caffeine were greatly helpful to prepare for the labs we did in class.
Thank you so much for the great content, I'm always looking forward to your new videos.
I have no clue what he's saying nor understand it but I like listening to him talk about science XD
I think this was mentioned in a later video but the dehydration step in aldol condensation follows an E1cb mechanism, which means that after the acidic proton is deprotonated on the beta-hydroxy ketone, the negative charge again moves to the oxygen of the ketone, then reforms the carbonyl and the double bond by pushing of a hydroxide. You can probably think of it like a reverse 1,4-conjugated addition.
Sick bongs dude
Man I’m so grateful he has a camera man now.its a total different show with the camera man
Awesome video... First one I have ever watched of your collection... And it did earn the subscription... Keep up the good work
Fantastic videos
Nice video!.
Maybe you could have used a bigger base instead of NaOH so it's more difficul for it to react with the 2 interior hidrogens (that I think are more acid than the other 3). Something like (CH3)3CH2OH.
I love to see people doing chemistry videos as detailed as this. Keep it up!
At 18:38 This answered that question I always had about the smell you get when touching metal.
the videos this guy make is the only thing I enjoy watching even if I can't understand it
Thanks, gonna use it on my friends now
