| 摘 要： | 本文拟在通过实验,叙述乙酸乙酯的皂化反应速率常数的测定,使用原来酯碱有相同起始浓度的所谓常规电导法进行测定,其实验结果不准确,与化学方法测定的文献值相差较大,分析误差产生的内在原因后,提出改进电导法的测定原理。克服了原来常规电导法的不足,并用实验数据加以论证,从而得出较满意的结果。

| Abstract: | In this paper, by means of experment, the determination of saponification reaction rate constant of ethye acetate was illustrated. Determined by normal conductivity method, the result is not exact, and the deviation from literature value which was determined by chemical method is relatively great, Through analysing the internal cause yielding deviation, this papee propose an improved conductivity method and its principle of determination. It overcome the weakness of normal conductivity method, be demostrated by ueing experimental date and a satisfied result is achieved. |
