We have synthesized 2-hydroxyethyl-triethylammonium bromide, then using it we have tried to prepare other salts. First we have used an ion exchange
column to obtain 2-hydroxyethyl-triethylammonium chloride, after several tries we didn't get any good results. Following this example : [emim][Br] +
KOH -> [emim][OH] + KBr [emim][OH] + CH3COOH -> [emim][CH3COO] + H2O We have tried to prepare 2-hydroxyethyl-triethylammonium acetate but for
some reasons, the reaction didn't take place. Can anyone help me to find an alternative method to synthesize those salts using
2-hydroxyethyl-triethylammonium bromide.

Classically, you treat the chloride with moist silver oxide- which reacts as if it was silver hydroxide- to get the quaternary hydroxide.
You can then react the hydroxide with hydrochloric acid to get the chloride salt.
