Production of ammonium salts of aromatic carboxylic acids |
| abstract |
A method for the production of ammonium salts of aromatic carboxylic acids by reaction of an aromatic carboxylic acid with ammonia in an aprotic solvent is disclosed. Said reaction is carried out in a closed vessel and a solution of the aromatic carboxylic acid in an aprotic solvent and gaseous ammonia are continuously introduced into the vessel, such that a partial pressure of ammonia of 0.1 to 3 bars is maintained in the gas chamber of the vessel and a suspension of the ammonium salt separates out in the aprotic solvent. The method permits the production of ammonium salts with defined crystal size and a narrow size distribution. |
