摘要

环己酮的制备是大学生有机化学基础实验室的一项重要实验。本文采用NaClO-TEMPO-TBAB催化氧化反应代替铬酸氧化反应，避免了浓硫酸和含铬废物的产生。同时，优化了反应条件，实现了实验规模小，缩短了操作时间，在实验中训练和提高了学生的操作技能。

Improvement of the Cyclohexanone Preparation Experiment

: 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.
