摘　　要：综述了双氧水氧化环己酮制备ε-己内酯(ε-CL)催化剂的研究新进展,包括含锡或镁的单金属催化剂、双金属催化剂及其他类型催化剂等。其中,单金属催化剂来源丰富但易流失和失活;双金属催化剂因存在协同效应催化效果相对较好;其他催化剂如生物酶因制备流程复杂,ε-CL分离较为困难。指出分子筛负载同时具有路易斯酸性及碱性的双金属氧化物催化剂用于双氧水氧化环己酮制备ε-CL具有很好的开发前景。The research progress in the catalysts for the cyclohexanone oxidization intoε-caprolactone(ε-CL)by hydrogen peroxide was reviewed,including single metal catalysts containing tin or magnesium,bimetallic catalysts and other types of catalysts.Single metal catalysts are rich in sources,but easy to be lost and deactivated;bimetallic catalysts have relatively good catalytic effect because of their synergistic effect;and other catalysts such as biological enzyme cause the difficult separation ofε-CL due to the complex preparation process.It was pointed out that the molecular sieve supported bimetallic oxide catalyst simultaneously with Lewis acidity and alkalinity was expected to be of a good development prospect for the oxidation of cyclohexanone intoε-CL by hydrogen peroxide.
