摘要
通过对硝基苯甲酸为原料经催化加氢合成对氨基苯甲酸的理论及实验研究 ,分析了温度、压力、催化剂用量、原料液浓度对反应过程的影响 ,并通过正交试验确定了反应的最佳工艺条件 .
The p aminobenzoic acid is synthesized by catalytic hydrogenation of p nitrobenzoic acid. The influences of reaction temperature, pressure, amount of catalyst and concentration of raw material on the yield of product are investigated. The optimum synthetic conditions are determined by the orthogonal experiments. The yield of product is above 85%.
