消去反应是一类重要的有机反应,也是高中阶段必须掌握的醇的重要性质。醇的消去反应在药物合成、香料香精的开发、农药的研发等有机化学领域涉及官能团转化内容时起到重要的桥梁作用。现行的高中各个版本的教材都对醇的消去反应有着比较详细的介绍,对高中生提出较高的能力要求。以人教版《有机化学》为例,在31面实验3-1介绍了乙醇消去制备乙烯的实验过程:将无水乙醇与95%左右的浓硫酸以体积比1:3混合, Elimination reaction is an important class of organic reactions, but also important high-level alcohol must master the nature of the stage. Alcohol elimination reaction in the synthesis of drugs, the development of flavors and fragrances, pesticides and other areas of organic chemistry involved in the conversion of functional groups play an important role in the bridge. Current high school textbooks of all versions have a more detailed description of the elimination of alcohol, high school students put forward higher ability requirements. Taking PEP “Organic Chemistry” as an example, Experiment 3-1 on the experiment of removing ethanol from 31 surface introduces the experiment process of preparing ethylene by alcohol elimination: mixing anhydrous ethanol with about 95% concentrated sulfuric acid in a volume ratio of 1: 3,
