| titleOfInvention | Production of alpha-(3-aminophenyl)ethylamine |
| abstract | PURPOSE: To obtain the subject compound such as a polymer curing agent in high selectivity by carrying out two-state reaction of m-nitroacetophenone through m-aminoacetophenone in the same solvent using a specific catalyst and additive. n CONSTITUTION: m-Nitroacetophenon expressed by formula I is catalytically reduced with hydrogen in the presence of a catalyst and a solvent to provide m-aminoacetophenon expressed by formula II. The solvent is then directly used to aminate the resultant compound with hydrogen and ammonia in the presence of a catalyst, a small amount of a weak acid or ammonium salt of the weak acid and afford α-(3-aminophenyl)ethylamine expressed by formula III. The aforementioned method can be advantageously carried out under conditions of a low temperature under a low pressure and the small amount of the weak acid or ammonium salt thereof can be added to suppress side reaction. The m-aminoacetophenone expressed by formula II may be obtained by taking out part or the total amount of the reaction product in the intermediate stage of the above-mentioned reaction and carrying out simple purification. n COPYRIGHT: (C)1991,JPO&Japio |
