Ⅰ. 反应速率常数、活化能的量热法测定
摘要:
用流动型微量量热法测定了在不同温度下乙酸和甲醇及乙醇的酯化反应的速率常数, 并籍助于阿累尼鸟斯公式测定了这些反应的活化能。为了检验此方法的可靠性, 测定了乙酸甲酯和乙酸乙酯水解反应(酯化反应的逆反应)的速率常数, 这一实验结果与根据酯化反应实验数据计算得到的结果相一致。

STUDIES ON THERMOKINETIC METHODS (Ⅰ) DETERMINATION OF REACTION RATE CONSTANTS AND ACTIVATION ENERGIES BY CALORIMETRY
Abstract:
The esterification rate constants of the acetic acid with the methanol and ethanol at various temperatures were determined by the flow microcalorimetry, while with the help of Arrhenius relation the activation energies of these reactions were determined.
In order to check the reliability of method, the hydrolysis (reversal reaction of esterification) rate constants of methyl and ethyl acetates were determined, the results of experiments are consistent with results of calculation from the data of esterification experiments.
