采用Benson基团贡献法估算了三醋酸甘油酯的合成反应热．计算结果表明：该反应的焓变分别为ΔHf1＝－41．1 kJ/mol、ΔHf2＝－12．3 kJ/mol、ΔHf3＝－12．3 kJ/mol ，所得的计算结果与实验测定数据基本相符合．考察了在采水条件下温度对三醋酸甘油酯合成的影响，建立了拟一级反应动力学模型，结果表明，该模型能较好的拟合实验数据．

The method of group contributions was applied to estimate the enthalpy of glycerol triacetate under the standard state.The results indicated that the enthalpy of glycerol triacetate wasΔH f1 =-41.1 kJ/mol、ΔHf2=-12.3 kJ/mol、ΔHf3=-12.3 kJ/mol ,which matched the experiment.The reactions were investigated under separating the water at different temperature.A approximate first reaction model was established,which recurred the experiment.
