Abstract:

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.

Key words: Cyclohexanol, Cyclohexanone, Catalytic oxidation, Phase transfer catalysis
