摘　　要：本文根据文献提出的几类可逆反应通用的微分动力学方程,建立了热导式量热计中可逆反应动力学的数学模型和不可逆反应动力学的数学模型,运用听导出的一级反应模型,处理了乙酸乙酯与丙酸乙酯在85%乙醇—水混合溶剂中的皂化反应,计算结果与文献值甚为符合,验证了有关理论公式的正确性。On the general differential kinetic equation proposed in previous article for several kinds of reversible reaction, some mathematical models of reversible reactions kinetics are suggested by using the basis of the thermokinetics transform equation and combining this equation with dimensionless parameter. As special exaniple of the models of reversible reactions etics, the mathematical models of first order and second order reaction kinetics are also derived. And the thermokinetics for saponification of the ethyl acetate and ethyl propinate have been studied at 25.0℃ in 85% ethyl alcohol aquous solution with the mathematical model of the first order reaction. The rate constants are in reasonable agreement with the values in literature, The relevant formulas are therefore, believed to be correct.
