摘要
研究以甲醇钠为催化剂，用碳酸二甲酯（ＤＭＣ）替代光气和２，４－二氨基甲苯合成２，４－ 甲苯二氨基甲酸甲酯反应．加入甲酸甲酯，可使２，４－甲苯二氨基甲酸甲酯的产率提高２０％， 反应中２，４－甲苯二甲酰胺和Ｎ－（２－甲基－５－氨基）苯基甲酰胺的生成对２，４－甲苯二氨基甲 酸甲酯产率的提高具有重要作用．以此为基础，推测了反应历程．
2,4-Toluene Dicarbamate (TDC) is synthesized from 2,4-Toluene Diamine and Dimethyl Carbonate using CH3ONa as a catalyst. The yield of TDC is increased about 20% when methyl formate is added. 2,4- Toluene Diformamide and N- (2-methyl-5-amino) phenyl formamide formed in the reaction play key roles to the improvement of TDC yield. The reaction mechanism is discussed.
