| titleOfInvention | Production process of p-aminobenzamide |
| abstract | The invention relates to a process for preparing p-aminobenzamide, which comprises the steps of carrying out catalytic esterification reaction on p-nitrobenzoic acid and alcohol to generate p-nitrobenzoate, and carrying out amidation reaction in an ammonia-alcohol solution in the presence of a hydrogenation catalyst and hydrogen to prepare the p-aminobenzamide. The method has the advantages of cheap and easily-obtained raw materials, simple and convenient operation, less waste water, high operation safety, high reaction selectivity, high product yield and purity and low cost. |
