摘要
以环己醇合成环己酮在大学有机化学基础实验教学中占有重要地位,但是目前实验教学主要使用的方法是重铬酸钠-浓硫酸氧化法,使用强腐蚀性的浓硫酸,并产生含铬强酸性有毒废液。本文采用NaClO-TEMPO-TBAB催化氧化反应,缩短实验时间,提高产率并实现了半微型化实验,在达到同样教学目的的同时避免了原有实验带来的铬污染和强酸问题。
The cyclohexanone preparation is an important experiment in fundamental organic chemistry laboratory for college students.In this paper,NaClO-TEMPO-TBAB catalytic oxidation reaction was used to replace chromic acid oxidation reaction,avoiding concentrated sulfuric acid and chromium-containing waste.At the same time,the reaction conditions were optimized to achieve small scale and shorten operating time which can train and improve students’operation skills in the experiment.
