Does anyone have a good cheap source of choline chloride in Australia? The chicken places here don't seem to sell it.
I am looking at playing around with a deep eutectic solvent and tlc. Several hundreg 6 to 1kg should do the job.
Cheers,

You could try health food places.
(Not that I have actually seen it but it is the best idea I could come up with. I don't have a "chicken place" nearby.)aga - 12-10-2017 at 13:00
As it happens i've been thinking of doing some DES experiments for ages, and got around buying the bits a few weeks (could be months) back.
Same situation here - no ChCl can be easily bought locally, then i remembered someone (blogfast? deltaH? dunno who) saying you can react choline
bitartrate with potatassium chloride in a simple metastasis reaction to get choline chloride and potassium bitartrate as the products.
Potassium bitartrate is grudgingly soluble in water which helps.
Choline bitartrate is sold as some kind of wonder-food, which is Good, as the purity is 99% (so it says on the label), and you can get it on Ebay.
Also good is that No-Salt Salt (KCl) is sold in the supermarket, although it needs recrystallising twice to get rid of the other junk,
So far i got white goop, but that is encouraging, so i'll do a utoob video on it IF it works as a DES along with the urea i already purified.

Thanks aga!
This is helpful. I shall do it that way then.

Having dissolved ChBit. and KCl, then mixed them, the KBit. drops out nicely, and in bulk.
Boiling down the ChCl solution looked like it was about to crystallise, so i put it in the fridge.
Turns out that the crystals are just more KBit.
The information i found that said that ChCl is 'reasonably soluble' is complete s**t. It is Very, if not Extremly soluble.
Next step will be filtering out the solids and then boil to dryness, probably take it all the way to melting at 302+ C and let it cool in some kind of
dessicator.
Maybe add some activated carbon before filtering to try to get rid of the yellow colour.
It's like CaCl2 all over again.Dr.Bob - 14-10-2017 at 05:12
Choline will be very soluble, and likely hygroscopic, so it may not ever form a nice solid. Just used a derivative the other day, comes as the
calcium salt, as the sodium salt is harder to get solid.aga - 14-10-2017 at 11:25
So far so good - i got pink stuff !
In the time it took to get that photo off the camera and resized, the pink turned to burnt
Oh well. Either i can try to salvage the unburnt stuff, or start again.G-Coupled - 14-10-2017 at 18:08
What caused the charring - did you have a heat source on it, or was it just in a desiccator or similar?
:(

I would not recommend drying chlorine chloride at a temp greater than 150 C. Today I had about 50g drying in an oven at 140(ish) C for 4 hours and had
a mostly dry powder. I decided to turn up the temp to 180 C in order to get it completely dry before storage. After leaving for about 10 minutes I
noticed a weird amine smell coming from the basement. I ran down and my white solid was turning brown, decomposing into some awful smelling products,
white vapors were seen as well. I can still smell the fishy smell in most of the house even after 30 minutes. Now I will have to repurify after the
hours and hours of boiling down/drying I already did.aga - 15-10-2017 at 12:56
There's no Beer in the video, so my standards might not be quite met gatosgr - 24-10-2017 at 12:53
I also had problems with choline chloride so I replaced it with trimethylglycine, it took me a lot of time to figure this out, their structures are
similar, I also had success with making new eutectic solvents by using molecules that are similar to the more traditional eutectic solvents.

Wooo !
Sounds interesting. Please give more details.Texium - 25-10-2017 at 05:14

Yeah back when I was messing with DES's I made that
same mistake, except instead of in a basement I was in a chemistry classroom full of students. Needless to say, they weren't too impressed by the
clouds of trimethylamine fumes and from then on dreaded my independent experiements.aga - 25-10-2017 at 11:10
