Abstract: Process for preparing salts K+ X-, where K+ is an organic cation and X- is an anion, by anion exchange, characterized in that a salt K+ Y-, where K+ is as defined above and Y- is an organic anion having a carboxylate, sulphonate or sulphate group, is used as starting material and K+ Y- is reacted with a protic acid HX whose pKa is lower than the pKa of the protic acid HY and, after the reaction the salt K+ X- obtained and the protic acid HY obtained are present in separate liquid phases.

Abstract: The invention relates to a method for purifying salts K
+ X
- , K
+ is any cation and X
- is an organic anion having at least 6 C atoms, characterized in that a) the salts K
+ X
- are present in compositions that contain water-soluble salts (K
+ )
n Y
n- as contaminants, K
+ being the aforementioned cation, Y
n- being an inorganic anion or an organic ion different from X
- having at most 10 C atoms, and n being 1, 2, or 3, b) the anions X
- of the salts K
+ X
- are transformed into the acids HX by adding a water-soluble hydrogen acid (H
+ )
m Z
m- , m being 1, 2, or 3, two phases being formed, an organic phase, which contains HX, and an aqueous phase, which contains the water-soluble salts (K
+ )
m Z
m- and (K
+ )
n Y
n- or acids (H
+ )
n Y
n- , c) the organic phase is removed, d) the aqueous phase is conducted over a strongly basic anion exchanger, which binds the anions Z
m- and Y
n- and releases OH
- , and thus an aqueous mixture, containing K
+ OH
- is obtained, and e) the organic phase (containing HX) and the obtained aqueous mixture (containing KOH) are reacted, possibly with the addition of further HX, to form K
+ X
- and H
2 O.
