摘要
由对苯二甲酸与异辛醇在ＳｎＣｌ_２非酸催化剂作用下酯化合成了对苯二甲酸二异辛酯。研究了酯化反应的动力学行为，提出酯化反应的速率方程（－ｄＣ_Ａ）／（ｄｔ）＝ｋＣ_Ａ，反应表观活化能Ｅ＝４０．ｋＪ／ｍｏｌ，反应速率常数ｋ＝３．８２×１０~４ｅｘｐ（－４８３７／Ｔ）。
The kinetics of the esterification of p-phthalic acid with isooctanol over SnCl2 type nonacid cat alyst was studied. The rate equation for the nonacid catalytic esterification was derived as -dC_A/dt = kC_A. The apparent activation energy E = 40. 22 kJ . mol￣(-1) and the rate constant k =3.82×10￣4exp(-4837/T).
