在《全日制十年制中学化学教学大纲》中增加了“消去反应”的条目,现根据中学教学内容所及,将有关的一些问题作一个简单介绍。消去反应(Elimination Reaetion)也叫消除反应。广义的说它包括:(1)脱氢、(2)脱X_2、(3)脱水、(4)脱HX、(5)脱羧、(6)脱氨,有的资料中还包括霍夫曼降级反应。但是目前一般认为消去反应是指醇类脱水或卤代烃脱HX而形
In the “Full-time 10-year Middle School Chemistry Teaching Syllabus”, an item of “elimination of reaction” was added. Based on the content of secondary school teaching, some relevant issues are briefly introduced. Elimination reaction is also called elimination reaction. Broadly speaking, it includes: (1) dehydrogenation, (2) de-X2, (3) dehydration, (4) de-HX, (5) decarboxylation, (6) deamination, and some materials include Huffman degradation. reaction. However, it is generally considered that the elimination reaction refers to the dehydration of alcohols or the removal of HX from halogenated hydrocarbons.
