Thats why you should just use DCM to extract the Acetic acid. It prevents you having to heat it and you can dry the AA/DCM before easily distilling off the DCM. This will give Glacial AA that is solid at room temp from my experience.
I am actually trying to concentrate acetic acid without even using other chemicals, such as fractional distillation and fractional freezing, but there is so much hassle to deal with.
@alDistractions I did the sodium acetate route many years ago, and at that time the ratio was slightly off so there was acetic acid in excess, which made heating essentially boiling acetic acid vapour to the atmosphere and turned the room into a tear gas room.
I tried fractional freezing with H2O2 without much success. I made several attempts, putting in the freezer inside of a glass vacuum flask/thermos, and so on. In the end the most effective way to concentrate it was in a shallow tray, evaporating at room temp for a few weeks. I wonder if this would work with vinegar. The dilute vinegar would have to be distilled first to get rid of the organic gunk. I made GAA using the surplus of sodium acetate I had accumulated from hydrolysis of amyl and ethyl acetate.
@@WaffleStaffel Unfortunately you can't concentrate vinegar the same way you did with hydrogen peroxide. Despite acetic acid and water don't form an azeotrope, their BP difference is so small that it requires a giga-long fractionating column or multiple passes to separate it to an appreciable level of concentration, it is therefore very impractical. (Although I would very much wanted to explore the science behind it.)
i think it would probably be more economical to just make it through catalyzed reduction of ethanol. i think the catalyst used for that particular reduction is gold but could be wrong and there's probably a better/cheaper one if you look. neat part about it is ethanol can make a lot of different things depending on the catalysts and temperature, for instance aluminum oxide (alumina, bauxite, metallic aluminum's passivization layer, whatever) is what i use for making my refrigerant (ethylene). i haven't actually tested making acetic acid from ethanol that way, but i think its been done and would work. would like to see someone try it on a smaller scale than industry but larger than small lab samples. in theory with enough catalyst and dialing the temp just right you should get close to 100% yield but gold is pretty expensive so i imagine it would be better to just do multiple passes after figuring out the temp.
Maybe once a year I'll get too lazy to pull out the litmus paper when trying to determine if the residue on a battery is acid from a leak or just some grease that migrated away from the connection terminals, and so I taste it. And once a year I'm reminded that that was the worst decision possible.
When you make the Sodium Acetate, could you go the route of crystallization instead of drying and grinding ? or would you still need to dry the crystals (so like why bother)..? Cool content too!
The sodium acetate should be now where near pure. Vinegar contains a lot of byproducts that will make their way into the sodium acetate. You might try recrystallizing the sodium acetate first.
@@ChemicalDistractions Before the sale was banned it was around £10/l but way cleaner than I see in North American videos. Same with the now vanished (as of last October) spirits of salt as a much nicer version of muriatic acid.
If they stoped selling sulfuric acid at Walmart I'd be in trouble. It's easily my most used chemical.... It's high boiling point, super strong, Insoluble if you just give it a calcium, and used in TONS of reactions
Never stop doing the “code yellow” alarm lmao
This man looking more and more unhinged in each video - love it
Thanks lol
Every school all over the world should have a "Code YELLOW"
MUST HAVE
Your channel is a hidden gem. Can't wait to see where it goes
Thank you! Hopefully it goes well
Top notch editing as usual. Lost it at the code yellow alarm. This might be my new favorite chemistry channel
2:42 for those wondering, sulfuric acid is also very very sour. Also burns your tongue
Most of my school chemistry ... ended in YELLOW , even my wee is YELLOW ( ? ) ........ DAVE™🛑
The way you tested the citric acid makes my mouth full of salaiva as if there is a pinnacle that is closer to me 😁😁😁😁
Is acetic acid dangerous?

sheesh yeah that's probably pretty time consuming... this video took hours of boiling off water and baking sodium acetate it's a really slow process
@alDistractions I did the sodium acetate route many years ago, and at that time the ratio was slightly off so there was acetic acid in excess, which made heating essentially boiling acetic acid vapour to the atmosphere and turned the room into a tear gas room.
Heh yeah I've been pretty happy with my diy fume hood. If I did that in a closed room without a fume hood I'd be gassed out

Is it possible to use oxalic acid ? For cleaner GAA ?

Seems like just keeping the heat lower that might have stopped The citric acid from burning

Sodium acetate forms crystallohydrate so drying is nessesary.
the crystals need to be dried either way and boiling off all the water is more efficient at getting everything out than recrystallization
Thanks for video.yes,lol,this stuff(distillations are are insanely time consuming.)been there before.great video😃.
Is It possible to concentrate acetic acid without distillation from magnesium acetate + oxalic acid?
Uhh idk... I'll look into it
dude this made me BUST
A nut?
Thank you so much! I can purifying acetic acid using Walmart stuff!
Love this video!
Thanks!

Organic natural vinegar definitely does. I should've clarified.. this is artificial cleaning vinegar made by adding acetic acid to water.
I thought u were gonna do ethyl acetate dean stark with 5% vinegar
Being in the UK, sulphuric acid is far too valuable for concentrating vinegar. I'll have to give this a go.
A liter is like $5 here

Lean in to the george carlin thomas the tank engine type editing harder. Jumping out from behind beakers throwing down science n shit. Love it.
Haha Tom and his yellows
glad i invested early in this channel, soon ill be able to retire
Hey I hope so man lol
Ok
Nice
Thanks!
Just make sulfuric acid from epsom salt. Problem solve
👍👍👍👍
