对用电导法测定乙酸乙酯皂化反应速率常数的条件进行了研究。结果表明 ,当乙酸乙酯的初始浓度略小于氢氧化钠的初始浓度时 ,可得到与二者初始浓度相同时类似的结果 ,而当乙酸乙酯的初始浓度略大于氢氧化钠的初始浓度时 ,则不宜用电导法测定此皂化反应的速率常数

The conditions of measuring the constant of saponify reaction with conductivity method are studied.when the initial concentration of acetic ether is smaller than the sodium hydroxide,the better results can be obtained as the acetic ether and sodium hydroxide have same initial concentration was.But the initial concentration of acetic ether is bigger than the sodium hydroxide,the conductivity method don′t fit to determin the constant of saponify reaction.
