| 摘 要： | 以30%H2O2 为氧化剂,用FeCl3 催化氧化环己醇可得到产率(基于环己醇)为 75%以上的环己酮,反应中无须加入相转移催化剂,考察了用量、催化剂、反应时间及反应温度对产率的影响.所用催化剂价廉易得且具有极佳的水溶性,分离回收容易,是一条绿色合成环己酮的好途径,克服了目前有机化学实验教材中采用浓HNO3、KCrO4 或KMnO4 氧化法存在污染大、反应时间长等缺点.

| Abstract: | Without phrase transfer catalyst, Cyclohexanone was prepared from cyclohexanol and hydrogen peroxide. The effect on reaction of factors including the amount of oxidant and catalyst, reaction time and temperature were accounted and the optimum conditions were found. Compared with that of teaching material in organic chemistry, which is pollutant and poisonous, the new way is more feasible and less poison and suitable for teaching experiment. Because the catalyst used in the reaction, FeCl_3, is handy, dissolvable, and recyclable as well. |
