摘　　要：环己烷氧化制备环己酮和环己醇是一个重要的工业过程,但目前满足绿色环保和便于工业化应用的催化剂或反应工艺很少,N-羟基邻苯二甲酰亚胺(NHPI)催化剂因其能在温和条件下有效地催化烃类自由基氧化而受到广泛关注.本文综述了近年来NHPI复合催化体系催化氧化环己烷的实验路线.分析表明NHPI复合催化剂能明显地提高环己烷的转化率和环己酮的选择性,但普遍存在反应时间长,热稳定性差,可回收率低等缺点.因而开发更高效的NHPI复合催化剂,对环己烷氧化工艺及其工业化应用具有重要的现实意义.Oxidation of cyclohexane to produce cyclohexanone and cyclohexanol is an important industrial process,but so far there are few catalyst and reaction process to meet the green environmental protection and convenient for industrial application.N-Hydroxyphthalimide（NHPI）catalyst has attracted much attention because of its effective catalytic effect of hydrocarbon radical oxidation under mild conditions.The process of cyclohexane oxidation catalyzed by NHPI composite catalytic systems in recent years was reviewed in this paper.Analysis showed that NHPI composite catalyst could obviously increase the conversion rate of cyclohexane and selectivity of cyclohexanone,but there generally exist some disadvantages of long reaction time,poor thermal stability and low recycling rate.Therefore,developing more efficient NHPI composite catalyst has an important practical significance in ocyclohexane oxidation process and its industrial application.
