Improvement and Innovation of Experimental Teaching for the Preparation of Diethyl Ether and Phenylethyl Ether

为了更好地满足创新型人才培养的教学需求，本文以分子间脱水法制备乙醚和Williamson合成法制备苯乙醚为实验主体，将延长式恒压滴液漏斗引入到乙醚和苯乙醚的反应装置中，并对其反应条件、反应装置和纯化方法进行优化与改良，有效提高反应产率和成功率。教学实验的改进增加了实验的创新性和综合性，提升了学生的学习深度和创新能力，进而提高有机化学实验课程教学质量和人才培养质量。
In order to better meet the teaching needs of innovative talents training, this paper takes the preparation of ether by the intermolecular dehydration method and phenylethyl ether by the Williamson synthesis method as the experiment main body, and introduces the extended constant pressure dropping funnel into the reaction device of ether and phenylethyl ether. In addition, the reaction conditions, reaction device and purification methods are optimized and improved to effectively improve the reaction yield and success rate. The teaching experiment improvement increases the innovation and comprehensiveness of the experiment, enhances the learning depth and innovation ability of the students, and further improves the teaching and talent training quality of the organic chemistry experiment course.
