酯化反应是中学有机化学体系中非常重要的反应类型,涉及碳链的变化、官能团的变化、平衡移动、有机物分离提纯、有机反应机理等许多知识;人教版《化学2》75面实验3-4,人教版选修5《有机化学基础》63面思考与交流部分均设置了对应的酯化反应实验进行探究。教材中酯化反应使用浓硫酸作为脱水剂和催化剂,但浓硫酸的强氧化性和脱水性使得反应中易发生炭化、氧化、成醚等副反应,同时形成的均相体系使得后处理
Esterification reaction is a very important type of reaction in the organic chemistry system of middle school. It involves many aspects such as the change of carbon chain, the change of functional group, the equilibrium movement, the separation and purification of organic matter and the organic reaction mechanism. -4, PEP 5 Elective 5 “Basics of Organic Chemistry” 63 aspects of thinking and communication are set up the corresponding esterification reaction experiment to explore. Materials used in the esterification reaction concentrated sulfuric acid as a dehydrating agent and catalyst, but strong sulfuric acid strong oxidizing and dehydration makes the reaction prone to carbonization, oxidation, ether and other side reactions, while the formation of the homogeneous system makes the post-processing
