The only thing that really worried me was the ether. There is nothing in the world more helpless and irresponsible and depraved than a man in the depths of an ether binge, and I knew we'd get into that rotten stuff pretty soon.
yesss as soon as I read ether I knewww 🤣
Insane movie/ book.
I should say this is a quote from Hunter S Thompson for those that don’t know.
@@Jamiefearon Yup I know the quote from Fear and Loathing in Las Vegas great movie HUGE mind fuck and I recommend it to everyone hehe
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.
we can't stay here, this is bat country
Now I'm no chemist.. But.. I still love your content, and you are great at making the chemistry feel pretty close to me. And also instilling respect for it, which is great because sometimes that's needed as well. Thanks, looking forward to the next one!
same. i am just here becquse i watched some nilered videos and youtube keeps suggesting chemistry videos. now i actually start to like chemistry. maybe i should study chemistry xD
Great video! Just worked with Diethyl Ether for the first time yesterday making metal complexes. Also somehow got a 108% yield 😅
That means you are too good at chemistry
@@chemdelic or bad at maths lol
@Doctor Whowhotheowl i asked my instructor about it he said there was probably some impurities somewhere. I was making a metal complex and there might’ve been some stuff that didn’t dissolve completely. The math was all good but yeah somehow went over the theoretical yield
@@itsjorge0477 Sounds like the big bang.
You probably just inhaled a little too much diethyl ether and you can't remember where you got the extra 8%
5:24 I would've loved a bit more explanation on HOW the peroxide formation is prevented by adding NaOH, KOH, etc. Great stuff btw❤
Koh and Naoh dont really prevent the formation of peroxides, from what i read they make alkali metal peroxides fall out of solution. So if you destill your ether ( what you should do regularly) you dont end up with a concentrated solution of your peroxides. Alkali metals and other stabilisers seem to reduce the peroxides.
@@georgkiesbauer337it is my understanding that sodium hydroxide catalyzes decomposition of THF hydroperoxide though.
These are the same cans I use to purchase. Getting both ether _and_ heptane from the same product is awesome.
Thanks for uploading!
Thanks for watching!
That bottle full of crystals is terrifying!
Love the videos and your sense of humor! Especially, the BYU peroxide crystals! Having seen their safety “measures” I gotta say I’m not exactly surprised.
One little suggestion I might give (by no means a critique) is to lower your thermometer down further into the neck of the distillation head. Lowering the bulb ensures good contact with the vapors and the temp difference of a few cm that close to the head is theoretical at best. When I was an Ochem TA we noticed a lot of students getting really varied temps on their distillations, so we had them lower their thermometers and the problem disappeared. Might be why you had some ether come over before the boiling point.
Keep up the good work I always look forward to watching your videos!
WATCH TIL THE END PEOPLE!
I am glad you gave me that last bit of information that I had not thought of. 2 days ago I did a fractional distillation of like 9 cans of starting fluid. Took me all day. First 3 cans I stored in plastic reagent bottles my wife brought me from the lab she works at. Before I was done collecting the next 3 cans worth, it had made those plastic bottles porous and looking like frosted glass; the plastic had cracked and it had leaked out into my freezer. Yay! So I cleaned it up and continued on and have stored all of my ether into a 2000mL flask until my glass reagent bottles arrive from Amazon. BUT I did not put any NaOH in the flask. 😮😅
I wasn't aware of the issues of storing ether. Thanks.
Will use this to explain why I haven’t been revising for my GCSE Chemistry exam
Are your chemical explanation sections with the drawing and fast talking inspired by Hamilton's pharmacopeia? I always loved those parts for some reason even though I had absolutely no idea whats going on LMAO.
It sure is! I love Hamilton’s pharmacopeia!
I've never messed with heptane but hexane is one of my favorite solvents for crystallization of certain chemicals.
Butylated hydroxytoluene is a cheap antioxidant that can be added to ethers you plan to store for long periods. It's what we use in our lab for long-term storage. No alkali contamination and it's easily separated by distillation.
I didn’t have any on hand but I agree with you!
when adding teflon tape to your diethyl ether bottle, you should make sure the tape is covering the threads and not the neck ring. your vapors are still escaping when you cover the neck ring.
Thank you! I did end up fixing it. I didn’t notice that it wasn’t fully covering. I appreciate it!
And just cooling the canister and not agitating it much, plus slowing the release to a good flow would be ideall.
Great videos man. You are the realest. Thank you for all your effort.
Side note: I remember spilling ether in the store room outside the fume hood and being like wtf, why am I lightheaded right now? I got out and it was okay but that shit can be sneaky in my experience. Not just from producing explosives spontaneously.
Alternative title: Turning starting fluid into stopping fluid
Great video as ever. Keep it up my friend.. we can't stop here it's bat country.
I learnt that chemistry is like fighting goku the hard way too awesome video king
Nice video! Straight to the point & concise. However, I was wondering: what made you choose sodium metal over something like, say, BHT? Also, next time, instead of spraying, penetrate the can (carefully, small hole. Cool down the can) & let the propellant gas out, then pour it into your flask. You'll get more of the starting fluid out, and waste less.
I didn’t have any BHT so I decided to use sodium metal. Also that is a good idea! I will try that next time! Thank you
Doesn’t that concerns about combustion by putting undue pressure on the can?
Definitely not an expert but I'm pretty sure it's a bad idea to puncture a container with high pressure, highly flammable gasses. Maybe spray it into a lidded container with a hole drilled in the top to just fit the nozzle in?
@@alexh5725 when you put the starting fluid in the freezer, it will prevent a lot of the ether / heptane from escaping the can. Most of the time the propellant is CO2
@@alexh5725 it's really not a big deal. it lets the Co2 escape and then you can just pour of the contents.
spray the can upside down to remove the gas leaving the liquid in the can, then puncture the can and you can pour the liquid out. You'll lose a lot less to evaporation.
I remember back when I was in college We actually discovered an Old bottle of ether that it formed peroxide crystals like this. of course me being the stupid undergrad working in the lab I was the one in charge of getting rid of it. For some reason none of the graduate students would come near it and wanted me to tell them when I was planning on removing it so that they could be absent. lol
5:22 is peak humor.
Just found this channel, very entertaining. Subbed
That picture of the crystals at 5:18 is not diethyl ether peroxide. Diethyl ether peroxide is a brown sticky goo - it doesn't form solid crystals like that. That could have been something like THF but why was it yellow? That honestly looked like a nitropropene/ nitroaldol result.
That’s what the source had down for peroxide formation. Interesting that Diethyl ether is a goo. Usually peroxide formation has any of the following
− Crystals
− Cloudiness
− String-like formations
− Stratification
So that’s interesting!
@@chemdelic A lot of ethers (especially the cyclic ones like THF) form crystalline peroxide solids, and are genuinely scary. They follow the scheme you proposed - you aren't wrong at all. Solid ether peroxides like to collect under the threads of the cap of the bottle/jar it's kept it and detonate when unscrewed. Diethyl ether peroxide isn't like that, it won't explode on you even if its been sitting in an oxygen environment for a year (for a crazy example). It doesn't form a crystal, and is genuinely like a tan/amber goo, sort of like what BHO from a marijuana extract looks like. Yeah it's super flammable and sort of unstable - yes all of those things - but because it's technically still in a liquid state it's not friction sensitive, and just stays a sticky amber goo.
That does not mean one can be ambivalent about ether peroxides though, because more or less every other common ether (maybe not MBTE) other than diethyl is sketchy and solid. Except benzyl peroxides that are used as polyester resin catalysts, but those still burn readily.
It's funny to see how I understand more and more of the chemistry videos when I go through high school. Just learnt about the process that involves the UV excitation.
is LSD really that hard to synthesise, I've read there's about half a dozen chemists in the world that produce it. Id love to see you do it as it seems to be a pretty confusing synthesis
If it was legal I’d already be trying. Though it is a hard synthesis due to you need lots of specialized skills, equipment, lighting, reagents, etc. My career goal is to work with psychoactives so maybe in the future!
Legit everytime I look something up and am not sure about it, you make a vid on it. I hope to keep up the streak lol
Love the _Sci Fi!_
Only BHT can inhibit peroxide formation - additionally to dark storage. The hydroxides can remove peroxide if already formed.
And ether has to be tested on peroxides with a acidified iodide solution everytime before heated.
Where possible DEE should be substituted by MTBE which cannot form peroxides, is slightly less volatile and therefore less flammable - otherwise you also need a dark, continously cold and xplosion safe place to store the DEE (a normal kitchen fridge isn't such a place...).
just something I noticed and thought Id point out: at 5:08 whats shown on the left is singlet oxygen and the diradical on the right is (I think, correct me if Im wrong on this) actually the normal triplet oxygen in the air, which is oddly enough more stable and inert than singlet oxygen, meaning this reaction actually releases light rather than being catalysed by it. again I might be completely wrong on this, but I checked and google search results seem to agree with me so I just thought Id mention it
Almost had to eat my pop tart in silence until I came across this 🙏🏼
Awesome video as always!
Thanks for the share 😊
Add a pinch of pearlite to your bpiling flask. It makes it boil near the surface of the fluid. Also a good idea to start with a ice salt bath when putting the fluid in. The ingredients in most starting fluid are diethyl ether, heptane, methyl tert butyl ether, and lubricant oil. 🤓
If the MDMS shows it contains methanol it would be wise to do a cold water wash before the distillation. In addition keep a good foam fire extinguisher and friend to help when distilling ether.
I couldn’t find the SDS for this specific one, but others like this didn’t have any methanol!
Love your videos and your channel!
Good to see you again king😏
Thank you for sharing this Cool information!
You explain things the best way possible!
I'd be interested to see if you could fractionally separate the various heptanes from the bulk product! It's not something I see explored much, but it could be interesting to see the process (even if there really isn't much point to doing so)
They may be similar for the most part but I'm sure there's things that benefit with the use of one or the other
Not worried about the mineral oil contamination from the sodium? Clearly should've ran it under the sink first.
Video idea:
Making water and salt from acid and base cause I don't feel like paying the bills
nice, simple, clean chemistry video :)
Dear DEA,
I am watching this video for entertainment purposes and I in no way intend to use diethyl ether for the synthesis of any controlled substances.
Dude.. !
Safety concern had my laughing hard, if it's not risky why bother. Keep it up you are doing great work
can you say what experiments failed? are we talking about those that you suggested in a community post?
Yes. Bromoethane, sodium ethoxide, and cloud chamber had some issues. I am reworking them right now and fixing it!
If you really start depressing try the old school vinegar and baking soda volcano, no fail possible, then inhale CO2 to calm down
From my experience with several different starting fluids, including a couple "50%“ advertised ones, you were probably better off keeping the first fraction separate, and fractioning the 40-70° bit, as by 40° you're already at ~20% heptane, and by 50° it's ~50% (mol%). And that's the VLE on N-heptane, but most of the content is branched chain with a lower BP, and probably comes over at even higher rate when much above the ether BP. Basically your ether is probably like 1/3+ alkanes. I never end up with more ether than alkanes. The 70-90° components are typically the majority of the volume. With a good column the “50%“ stuff usually gets close to 50% in volume of pretty pure ether, but not quite. Adding cold to a 2-neck through a straw/gas adapter with the setup already assembled and keeping condenser and receiver ice cold helps measurably (but not dramatically) with losses.
Ah. Do a "stripping run" with a standard still, then break out the column still the second time around. Good thinking: you can run a lot faster (given fixed heat source and column size) the first time through, then be precise when the volumes are lower.
I did something similar when (ahem) "purifying an aqueous solution of hydroxyl-substituted ethane via exploitation of relative vapor pressures."
Nice blade ❤
I had significant aldehyde contamination when I did this, as my sodium built up a reddish/orange crust from aldol condensations. Stirring the ether for several days and letting the stir bar knock off the buildup pulled way more crap out than I was expecting their to be
yo i inhaled that
Love your work! Comenting for the algorithm 🌻
Could've attached a hose to the spray nozzle tip after removing the aerosolizer.
Looks like some fun times ❤
Nice 👍🏻
👍
I keep hearing Jim from the office
I love your videos!
If you turn the cans upside down then spray them it'll decompress the cans while keeping the starting fluid inside. Once they get flat, poke 2 holes and pour out the fluid
finally
Is it ok to have an open flame near by when distilling? That way you'll know if the the the the concentration of fumes in the room are to high.
Quick question. If the peroxidation is formed by UV reaction, wouldnt it be good to wrap the bottle in foil to insulate it from UV. I know thats what they do for lab TLC stains
Yes it is! That’s why I put in amber glass bottles
So tell us what happened with your other experiments remember failures are just as exciting as successes.....
Just shake it and.... 💥 Lol
Turn the cam upside down. Press the nozzle. Drain the aerosol. Once you’re confident that it is drained and push it a few times and then put it in the fridge. Use a church key on the bottom lip. And pour. Watch your eyes. It can get spicy.
Great video!
💜💜💜💜💜
Hold the can up side down and spray. The propellant will come out without the liquid. Then you can use a can punch to put a hole in the base of the can and pour it out.
No one can best @Jamie Fearon's comment lmao
Those Walmart starting fluid cans contain a cylinder lubricant that is heavy boil point and you do not want it for an extraction
Bro, someone needs to show you how to use teflon tape. Wrap it the other way and it will pull tight against the threads.
Meow burn the whole damn place down or don't. Probably not I wouldn't
Do you think there’s enough diethyl either in your hexane fraction that you should worry about peroxide formation?
Likely not since there shouldn’t be that much in it! You could still put over sodium if extremely worried
I don't always do drugs, but yes
you can now recreate fear and loathing circus scene
Wish we had this in Canada
man ether scares me.
Step 1. Distill heptane and diethyl ether
Step 2. Use sodium to prevent peroxides
Step 3. Buy more sodium metal
Step 4. Use heptanes to store sodium metal
Step 5. ???
Step 6. Distill heptane and diethyl ether
This extraction was done by Nurd Rage 6 years ago.
can you recommend some books on organic chemistry to get close to your level? Love your content Im absolutely hooked!

Here is a good one!
@@chemdelic thanks. Im on it.
Been meaning to do this for a while now - ether is pricey but tbf, I usually replace its use with DCM…just seems lesss…um…explodey?😮
hhmmm.... what if you sprayed it into glycerin first? it'd help break any azetrope and the boiling/freezing points of glycerin and heptane/ether is much further apart than a straight distillation. I'm probably missing something with this 'meh' idea.
Would diethyl either turn into alcohol in someone's system? I had starting fluid in a container and added water to it so I had more to clean a carburetor. I almost passed out from the fumes after awhile. I have regular breathalyzers and scared it's gonna make me fail 🤦🏻♂️
Ok so what about L O N G ethers like polyethylene glycol? Do they form peroxides as well?
Is that how PEG works as a laxative? lololol
Not sure. I would have to check!
Only a certain amount of time until you start extracting dmt and LSD 😂
I accidentally broke a can of starting fluid so I put it in an amber jar like yours, will that form The peroxides?
Perhaps. I’d do a peroxide test to make sure
Can you do formaldehyde? I Need It for my school project
As a big fan of N02 what is huffing ether like?
I’ve never done it on purpose but it smells nice to me
@@chemdelic I've heard it has a longer lasting more intense "aroma" compared to nitrous oxide, I love to thoroughly research it one day.
NO2 is Nitrogen Dioxide and it’s a brown poisonous gas with fatal consequences… N2O on the other hand is a semi-enjoyable inhalant that is possibly the shortest acting narcotic ever
What's diphenyl heptane?? For ??
There are only diethyl ether and heptane from these
@@chemdelic same thing .....okay why is heptane a precursor to a FULLY Synthetic opioid for example....here....ok...., I'll re-ask the question 🙄......what is it ?
Lysergic Acid when
😂🐣😅
Hate that phrase store it over. You mean store sodium hydroxide in the ether?
I know this intro from 2010… do you have a template for it?
I bought it on some website like 2months ago. I have no idea where I got it tbh😂
Is it for Adobe After Effects?? @chemdelic
For your next video. You should make the red pill.

Hey chemdelic! Do you use vacuum for reduced pressure/temp distillations ever? I’m building an aspirator setup with water pumps to distill off some volatile solvents near room temp. I don’t want a pump due to the fact I don’t need a perfect vacuum.
Just wanted to hear whether you’ve gotten into that yet and I’d love to see you attempt a build similar to mine which I got from nurd rages video. I got everything for about $60 and I even have an extra pump on the way and if you want it for a video I’ll send it your way!
How would you recommend I equalize pressure in the vessel? I won’t be using a pressure gauge to start. I’m thinking about getting a stopcock pressure adapter so I can close it and then shut off the pump. I’m just not sure how safe a stopcock is for equalizing the pressure or whether that’s standard or not. I don’t have a manifold or anything and I’m just shooting for 75mmHg.
If you have any advice or resources please let me know and I’d love to see what you come up with and I think it would be a great video and project idea to build an aspirator setup to pull vacuum.
Keep up with the great videos, I love your amateur style especially as an amateur myself working on some kratom projects! Been a blast so far and seeing great success. Keep up the good work fellow bee ;)
Thank you! You can buy pressure regulator attachments for glassware too. I’d also recommend if you can find a pressure gauge to use it. I don’t personally use a water aspirator so I can’t give too much advice on it. I just use a rotary vane oil vacuum pump. If you take a look at my benzaldehyde video, it shows the use of a vacuum distillation. Though I really need a gauge for mine! As for resources, many various organic chemistry books that focus on laboratory techniques and preparation should give information on that. You can also find MANY videos on RUclips from schools showing how to set up and do a vacuum distillation. Thank you for watching!
I'm a big fan of DIY cost savings, but vevor sells a water recirculating vacuum pump identical to some that are sold for $500+, for $180 on Amazon. Ive had one for damn near three years, have gotten at least 500hrs of runtime out of it, ran it for roughly 38hrs straight one time, and other than some mild corrosion (from when I was experimenting with using salt water to take advantage of its lower freezing point and higher capacity to transfer heat. My conclusion is that the headache outweighs the benefits) there isnt a damn thing wrong with it, and I honestly have no complaints.
I caution you that it's not exactly quiet, but it's a steady droning that's far less obnoxious than most vacuum pumps/compressors.
Due to the nature of its design, as it runs, the motor that simultaneously runs the pump and the cooling fan gets hot, and despite having pretty well designed heat sinks, begins to heat the water, which in turn reduces the efficiency of the vacuum.
I removed part of the plastic enclosure around the motor and added a second fan to help keep things cool.
I then got a little carried away with increasing the total volume of water.
I had two 100qt coolers collecting dust, a spare metal storage rack, and bought polyethylene tubing, vinyl tubing, and hose clamps, from home depot and bought some plastic ball valves and a small aquarium pump from amazon (not entirely necessary)
I placed the coolers on the bottom and middle of the three shelf rack, with the pump on the top shelf. Using polyethylene tubing and zip ties I fashioned coils (think moonshine still) that fit nicely into the coolers.
I then fit a ball valve to each of the drain ports for the coolers. The bottom one is a discharge for warm water, and the middle is directed into the bottom cooler. Crushed ice goes into the top cooler and water goes into the bottom. The polyethylene coils are all connected. The end coming out of the middle cooler connects to the input for your condenser. Other than that you can route the tubing however you want. I'd connect the second vacuum line to the outlet on the condenser, connect the aquarium pump to the bottom end of the coils open in the bottom cooler, and run the outlet line from the circulator down into the bottom cooler. I also ran a hose from the top port on the circulator to the bottom cooler which functioned as an overflow. Drain the bottom cooler, refill it with the melted ice, and replace ice as needed.
I maintained 0.00073506034mmHg for 38hrs while running a fractional vacuum distillation.
I have a ball valve hooked up to a plastic tee on my vacuum line that I use to bleed the vacuum.
