Synthesis and Physical Properties of Choline Carboxylate Ionic Liquids

 JOURNAL OF CHEMICAL & ENGINEERING DATA 57(8):2191-2196

Hi, the method of preparing a eutectic ionic liquid from Choline is similar in principle to the method that I used in my publications to prepare ammonium and phosphonium eutectic ionic liquids. Refer to my publications and read the experimental section to have a general idea of the procedure. Good Luck.

We did it with electrodialysis (Separation and Purification Technology 97 (2012) 90–95), but there 's still quite some NaCl remaining. The easiest way to get pure choline acetate is neutralization of choline hydroxide (which is a strong base) with acetic acid, but you 'll need fresh choline hydroxide as it deteriorates quite fast. Actually, you 'll have to synthezise it yourself or eventually purify commercial product as it is often deteriorated to a large extent during transport.

Hi everyone,

I am looking about information about possibility of intravenous injection of Ionic liquids for example Colline acetate which contains drug?

thanks

what can be the procedure from choline chloride for the prepration of choline acetate??
