| 摘要 | Process for preparing salts K+ X−, where K+ is an organic cation and X− is an anion, by anion exchange, wherein a salt K+ Y−, where K+ is as defined above and Y− is an organic anion having a carboxylate, sulfonate or sulfate group, is used as starting material andK+ Y− is reacted with a hydrogen acid HX whose pKa is less than the pKa of the hydrogen acid HY andafter the reaction, the salt K+ X− obtained and the hydrogen acid HY obtained are present in separate liquid phases. | ||

| 主权项 | 1. A process for preparing salts K+ X−, where K+ is an organic cation and X− is an anion, by anion exchange, wherein a salt K+ Y−, where K+ is as defined above and Y− is an organic anion having a carboxylate, sulfonate or sulfate group, is used as starting material and K+ Y− is reacted with a hydrogen acid HX whose pKa is less than the pKa of the hydrogen acid HY and after the reaction, the salt K+ X− obtained and the hydrogen acid HY obtained are present in separate liquid phases. | ||
