实验室制备溴苯在新课程人教版教材中是被删除的内容,而它在近几年的高考中却又是常考的有机化学实验,如何处理这块被删掉却要考查的内容呢?我看还得从分析删除的原因来看,在2000年以前的人教版——图一,无论是在实验进行过程中还是在实验进行后污染问题都很严重,不符合绿色化学理念,所以新课程的人教版化学教科书采取了回避的措施,删去溴苯的实验室制法的内容,仅仅用文字描述的方法叙述了溴与苯在催化剂条件下可以发生取 The preparation of bromobenzene in the laboratory is a deleted item in the new curriculum teaching materials, and it is an often-tested organic chemistry experiment in recent college entrance examinations. How to deal with this deleted but examined content? In terms of the reasons for the analysis and deletion, I think that the PEP version before 2000, Figure 1, is very serious both in the course of the experiment and after the experiment. It is not consistent with the concept of green chemistry. Therefore, the PEP chemistry textbook for the new course took evasive measures by deleting the contents of the laboratory process for bromobenzene, and described the bromine and benzene in the condition of the catalyst only by a written description.
