摘　　要：乙酸乙酯的水解实验是现行高中有机化学教学内容中的重要实验,教材中提出通过观察酯层消失的时间差异来判断水解速率的差别,在实际操作过程中实验效果并不理想。借助手持技术分别探究了乙酸乙酯在中性、酸性、碱性、不同温度条件下的水解速率情况,并借助相关知识理论分析了乙酸乙酯在酸性和碱性条件下水解速率的差异,旨在帮助教师和学生深度理解乙酸乙酯发生水解的条件及规律。The hydrolysis experiment of ethyl acetate is an important experiment in the current organic chemistry teaching content of senior high school.The textbook proposes to judge the difference of hydrolysis rate by observing the time difference of ester layer disappearance.The experimental effect is not ideal in the actual operation process.With the help of handheld technology,the hydrolysis rates of ethyl acetate under neutral,acidic,alkaline and different temperatures were explored,and the differences of hydrolysis rates of ethyl acetate under acidic and alkaline conditions were analyzed with the help of relevant knowledge theory,in order to help teachers and students deeply understand the conditions and laws of ethyl acetate hydrolysis.
