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.

期刊介绍： University Chemistry is an educational research academic journal supervised by the Ministry of Education and co-sponsored by Peking University and the Chinese Chemical Society. It was founded in 1986 and changed to a monthly publication in January 2016. Its purpose is to promote and deepen the reform of university chemistry education and serve to improve the level of chemistry teaching in my country. The main columns are: Today's Chemistry, Teaching Research and Reform, Knowledge Introduction, Chemical Experiments, Teacher-Student Chats, Future Chemists, etc. The journal has been included in many databases such as China Journal Network Full-text Database, Wanfang Database, Taiwan Huayi Database, Chinese Science and Technology Journal Database (Full-text Edition), and American Chemical Abstracts.
