Abstract
The present invention relates to a N-hydroxyl cyclic imide compound obtained by reacting a polycarboxylic acid cyclic anhydride, a polycarboxylic acid or a mixture thereof with hydroxylamine or a salt thereof in an organic solvent under dehydration condition. The polycarboxylic acid cyclic anhydride can be succinic acid anhydride, glutaric acid anhydride and the like. The polycarboxylic acid can be succinic acid, glutaric acid, adipic acid and the like. In this method, an organic solvent capable of forming an azeotropic mixture with water is preferably used as a whole or a portion of the reaction solvent. The water within the reaction system can be removed by azeotropic boiling with the organic solvent during the reaction. By using this method, it is thus able to prepare the N-hydroxyl cyclic imide compound in good yield no matter which polycarboxylic acid cyclic anhydride or polycarboxylic acid is used.
