摘　　要：研究了对苯二甲酸法合成对苯二甲酰胺的反应过程,考察了溶剂、温度、时间等反应条件对目的产物收率的影响。结果表明合成对苯二甲酰胺的优化条件为:用适当量的乙二醇溶解对苯二甲酸二甲酯,60℃常压通氨气反应8h,对苯二甲酰胺收率可达94%。The process of dimethylterephthalate amidation to form 1,4-benzenedicarboxamide was studied.It was found that ethyleneglycol was the suitable reaction medium.The suitable reaction conditions for 1,4-benzenedicarboxamide synthesis were:using right quantity of ethyleneglycol to dissolve dimethylterephthalate,carrying out the reaction at 60℃ under normal pressure for 8 hours.Thus,the yield of 1,4-benzenedicarboxamide is up to 94%.And the 80% of ethyleneglycol could be recycled.
