摘　　要：研究了在新型相转移催化剂作用下苄叉二氯水解反应过程的动力学。在实验数据的基础上,建立苄叉二氯的水解反应动力学模型,并根据动力学数据进行参数估值,求得了90、100、110℃下表观反应速率常数分别为0.01674、0.02014、0.02286min-1,以及反应的活化能E=17.73kJ/mol,指前因子A=6.031min-1。苄叉二氯的最佳的水解工艺条件为温度100℃,水相与有机相的初始质量比例为2∶1,反应时间3h。经模型检验,发现模型与实验数据的吻和程度较好。The kinetic of hydrolysis of benzal chloride was studied by using a new kind .f phase transfer catalyst in this paper. The value of the apparent rate constant and reaction activity energy were gained through estimating the parameters of the kinetic model on the base of data of experiment. The activity energy was 17.73KJ/mol in the temperature range from 90℃ to 110℃ and the index was A=6.031min^-1. The proper hydrolysis reaction temperature of benzal chloride was 100℃ and the initial quality rate of water phase and organie phase was 2：1,reaction time was 3 hours. By verifying the model, the value of model calculated coincided with the experiment value was obtained.
