本文采用自制的绝热式自动量热计,对两个反应体系进行了一级反应的绝热式热动力学研究.速率常数的计算结果在误差范围内,与文献值符合均好.本文还在实验数据处理中提出了局外过程热效应的线性校正法.

On the basis of the thermokinetic transform equations proposed by one of the authors (Y. Dent, 1985), an adiabatic thermokinetic study of two first-order reaction systems, the alkaline hydrolysis of benzoic ester in aqueous alcohol and of benzyl chloride in aqueous DMSO, has been undertaken. The calculated rate constants of these two reactions agree with the values in the literature. A linear correction method for external heat effects is suggested.
