以尼龙酸、甲醇为原料、对甲苯磺酸为催化剂，通过酯化反应合成尼龙酸二甲酯。根据反应过程中反应混合物酸值的变化跟踪反应，研究反应规律，建立了不分水条件下该反应体系的酯化反应动力学模型。计算结果表明，在55~65℃条件下合成尼龙酸二甲酯合成的正、逆反应对各组分均为1.3级反应，正、逆反应的表观活化能分别为6.291×104 J·mol-1、4.768×104 J·mol-1，指前因子分别为5.73×106、1.26×104。正、逆反应的速率常数均与催化剂浓度（用量）成0.3的指数关系。模型值与实验值相符，显示了该模型的正确性。

The dimethyl adipate was synthesized through esterification reaction with nylon sour and methano using toluene-p-sulfonic acid as catalyst. Based on the acid value change of reaction mixture, the reaction was traced and the reaction rule was studied, and the kinetics model was established with the water no diversion. By kinetic calculation, it was obtained that the overall order of positive reaction and side reaction was 1.3 on 55~65℃, the apparent activation energy to positive reaction and side reaction was 62910J/mol and 47680J/mol, the frequency factor to positive reaction and side reaction was 5.73×106、1.26×104, the positive rate constant and side rate constant varied with the level of catalyst,they were both accord with exponential relationship of 0.3. The model values consistent with the experimental value, showed the correctness of the model.
