环己酮制备实验的改进
A Study on Improvement of the Preparation of Cyclohexanone
摘要
Abstract
"The preparation of cyclohexanone"has been listed as a typical experiment of Organic Chemistry Experiments in chemistry and chem-ical engineering majors.Cyclohexanone is prepared by oxidizing cyclohexanol with dichromic acid or sodium hypochlorite,which,however,will inevitably lead to environmental pollution caused by heavy metal chromium or exposure of students to irritant and toxic chlorine gas generate from sodium hypochlorite.In this study,environment friendly hydrogen peroxide is used as an oxidant.The effects of catalyst,buffer reagent,and tem-perature on this oxidation reaction were investigated.It was found that the yield of cyclohexanone was about 60%when Fe3+was used as cata-lyst,NaH2 PO4 as buffer,H2O2 as oxidant to oxidize cyclohexanol under reflux condition.关键词
