乙酸和乙醇的酯化反应实验改进

The esterification reaction modification of acetic acid and ethanol

乙醇和乙酸的酯化反应是高中一个重要的教学演示实验,通过使用分液漏斗、具支试管、球形干燥管组合的实验装置和采用磺酸树脂作为催化剂两方面对教材中实验进行了改进,实践证明,改进后的实验产物转化率高,实验现象明显,达到了绿色化学的实验要求。

The esterification of acetic acid and ethanol experiment is an important teaching demonstration experiment in senior high school.The author improved the experiment from two aspect,which is,using the reparatory funnel,with side tube,the spherical drying tube combination experiment device and using sulfonic acid resin as catalyst.It proved that the result conversion rate is high and the phenomenon is obvious after improving,which meet the requirements of the green chemistry experiment.
