摘　　要：采用RD496-CK2000微热量计测定了5-氯水杨醛缩2,5-二甲基苯胺(CHMB)的液相生成反应热动力学曲线。根据物理化学的基本原理推导的等温等压下不可逆化学反应的热动力学研究方程,计算了该反应的热动力学参数(活化焓、活化熵及活化自由能)、速率常数和动力学参数(表观活化能、指前因子及反应级数)。The thermokinetic curve of the formation reaction of 5-chloro-2-hydroxybenzaldehyde-2, 5- dimethylbenzenamine in liquid-phase was investigated using an RD496-CK2000 microcalorimeter. The thermokinetic equations for non-reversible reactions at the constant temperature and pressure were derived based on the principle of physical chemistry. On the base of thermodynamic equations, thermokinetic parameters （the activation enthalpy, the activation entropy and the activation free energy ） , the rate constant and kinetic parameters （the activation energy, the pre-exponential factor and the reaction order） were calculated.
