Making Diethyl Ether 

Love when I come across new quality home chemistry channels… maybe someday I’ll apply what my subconscious has absorbed. Seriously these skills could be as useful as foraging skills in a weird future

Nothing is more depraved than a man in the depths of an ether binge

This channel is much better than the Nile Red channel is. Especially these days. Keep up the great work!

honestly, a 45% yield for an ether synthesis is pretty good

You're crazy man, you pump out geniunely high quality content so quickly. I'm excited to see where this youtube journey takes you.

First. But seriously, this is a GREAT channel!

O shit. New chemistry Channel. Nice production quality. Subscribed.

what i always do for bigger synthethis of ether is just place a small reflux condensor on top and hook it up to a PID loop to drop back everything until the vapor coming out of the top of the condensor is 36-40°C

To increase the efficiency of the reaction, it is necessary to shift the equilibrium, and this can be done by removing water, and for this you need to put a glass trap with the ability to drain the desired layer. When you use a dephlegmator - you don't need to wet it, just blow it with air from the outside - put a fan.

Thank you! I saw at least one video (either from "nile red", or "chemplayer" or "dougs lab"), where the synthesis of diethyl ether took place in the presence of sand (in the 3-necked flask). I can't remember right now, what the purpose of the sand was, but maybe it is useful to improve your yield of the final product. But the starting materials are quite cheap, so don't mind too much.

I’m pretty sure the reaction to form diethyl ether from ethanol is an equilibrium reaction, so a Dean Stark trap may be useful

a taller column would also help if you happened to have one. the 2-4 ft columns are often wildly unnecessary for a lot of distillation/extraction, but certain fractions it is vital.

Deserves more views!

Excellent video my guy! please make more!

The column doesn't work in this synthesis. The point of heating to 140°C is that you distill off both water and ether. If the water remains, the reaction stops. In the industrial production the distillate is distilled again in spite of side products. Ethanol returns, and the crude ether is directed to next purification steps.

Maybe another explanation for the low yield, at 4:12 you leave ~200 ml and come back to a lot less the next morning, probably some ether evaporated overnight.

If your reaction temperature was too high, most of the loss was probably in the dehydration of ethanol, making a bunch of ethylene gas.

Nice. Always wanted to do diethylether by myself but didn't had a recipe

diethyl ether, my beloved

Difficulties I have had in this reaction is the formation of both ethyl sulfate and acetaldehyde.

can dilute sulfuric be used instead of concentrated? let's say 70% sulfuric as far as I understand, the important step is the reaction temperature which should not exceed 140°C, wich is the boiling point of 60% sulfuric acid, so 70% should be fine, right?

Useful things to know if you don’t have an Ether Bunny to bring you presents of ether!

Excellent. 👍

These videos are great👍, vaguely reminds me of nile red

I think you lost some when it sat overnight with the watch glass on top of the beaker, but maybe the calcium chloride had something to do with the volume change too idk.

The original English name was "sweet oil of vitriol" which I think is so charming!

So just use any acid that has a conjugate base that is non-nucleophilic, right? So HCl here would not be a good choice, but maybe nitric acid could work?

bruh how you only have 5k subs, this like 250k sub quality

How do u calculate the yield?

Why do I feel like a chemist when I'm nerding out over making different metal alloys 🤷🤷. Other than my irrelevance, nice video as always!

Oh yeaa another good upload

i love making ether great fun

When the temperature is way to high for this reaction, Ethene Gas (CH2=CH2) is formed, this could help to account for the small yield...

If you can flush the head space of your bottle with an inert gas you would extend the shelf life

Great high quality content! What was the inhibitor?

Please make vedio on dimethyl ether

Alternative title: making some kawaii chemical... that is until it finds an ignition source

The owls are not what they seem

We made diethyl ether, but its smell is so strong that it hurts our noses. We are having a hard time even smelling it. Do you think we made a mistake?

0:50 Looks like a NileRed video! But whithout forgetting an ingredient 😂

Remember viewers, the more useful a video is, the more likely it is to disappear. Take notes, because one day soon even the tamest of syntheses will vanish in a puff of blue smoke.

Hello, how do you remove the hydroquinone? We studied to but KOH inside, and then remove it. Does the hydroquinone not distribute the reaction?

Hi, Why you cold reaction in start time?

Super! Thank you very much!

Distilling ethers... bold! ;) Okay-ish in this case when the ether was freshly made. But generally questionable. It is one if the reasons for the myth chemistry were constantly exploding. Well... they do, if you distill old ethers. ;)

Reduce the amount of voltage to the pot. Too much energy going into mantle. You can maintain pot temp with lower voltage.

Can you please try to make dipropyl and dibutyl ether?

Nice

big fan

Use it to get high

Also please share the reference literature it will be highly appreciated

nice vid bro, what college did u graduate from?

Well at least u know why you had a small yield.

*looks at the thumbnail* Sir, that's a bird

Why do ethers form peroxide?

How old is that heating mantle?

If the temp was too high will not there be some ethanol in it.... anyone ?

Why has nobody mentioned that it’s far easier and cheaper to obtain this compound from common automotive starting fluid? Just distill out the lubricating oil.

I'm interested to see if your diethyl ether will support a Grignard reaction. Diethyl ether can be hard to clean.up. If it doesn't work try distilling it over sodium. You might want to test it on a small scale first. Years ago diethyl ether was used for a general anesthetic. A person who had been put to sleep this way smelled of diethyl ether for days. In the days of my childhood there was an old wives tale circulated by doctors that ALL children had to have their tonsils removed and in 1973 I saw whole family of children taken into the local hospital and all their tonsils were removed in one day. I was receiving from a broken.ankle myself. Most insurance policies do not cover tonsil removal.

Sick

What is the purity of diethyl ether?

Aus Belgien und Nederland diethyl ether Sie könen kufen in alles apotek an. Mit zonder kontrol.

Diethyl ether can get you high as hell, gotta be careful not to inhale it otherwise you WILL get high and knock you unconsious

Bump

Can I just have some? I got some experiments I wanna do ;)

Looks like a spider

I wanna drink that

I love you

Batman chemical

Making meth thanks 😅
