采用自建动态酯化反应实验装置，研究了以磷钨杂多酸作为催化剂，由己二酸和异辛醇合成己二酸二异辛酯的反应条件．在研究中．我们根据杂多酸催化己二酸二异辛酯液相合成反应的特点，导出了非等温条件下的反应速率方程，并以此为基础，对不同实验条件的多组实验数据进行了动力学处理．大量计算结果表明，杂多酸催化己二酸二异辛酯的合成反应服从二级动力学模型，对己二酸和异辛醇来说，反应级次均为一级；对杂多酸催化剂来说，反应级次为二级．该反应表观反应活化能为１０４．２６ｋＪ／ｍｏｌ，指前因子为３．６１×１０（１３）Ｌ·ｍｏｌ（－１）·ｍｉｎ（－１）．
The reaction conditions for the synthesis of diisooctyl adipate from adipic acid and isooctanol were studied using a self-built kinetic esterification reactor. In research. Based on the characteristics of heteropolyacid-catalyzed synthesis of diisohexyl adipate in liquid phase, we deduced the reaction rate equation under non-isothermal conditions. Based on this, the kinetic data of several groups of experimental data under different experimental conditions were obtained. deal with. A large number of calculations show that heteropolyacid-catalyzed synthesis of diisooctyl adipate obeys the second-order kinetic model, and for adipic acid and iso-octanol, the reaction order is one order. For heteropolyacid catalyst For the reaction level is two. The apparent activation energy of the reaction was 104.26kJ / mol and the pre-exponential factor was 3.61 × 10 (13) L · mol (-1) · min (-1).
