环己基苯氧化-分解联产苯酚和环己酮技术的研究进展Ⅱ.环己基苯氧化-分解制备苯酚和环己酮

摘要

Recently,a new process has been proposed for the co-production of phenol and cyclohexanone from cyclohexylbenzene,including three main steps:the hydroalkylation of benzene,the peroxidation of cyclohexylbenzene and the decomposition of the hydroperoxide products. In this paper,we summarized the research progresses in the development of the cyclohexylbenzene’s catalytical oxygenolysis at home and abroad. Great importance was especially attached on the reaction chemistry and mechanism,catalysts and process conditions,as well as the process flows. Meanwhile,future outlook was also depicted on co-synthesis technique for phenol and cyclohexanone.%苯通过加氢烷基化反应制备环己基苯（CHB），再经氧化-分解反应可同时得到苯酚和环己酮，是近年发展起来的苯酚和环已酮生产的新途径。综述了该技术国内外研究开发的进展，重点介绍了CHB氧化和分解过程的反应化学、催化机理、催化剂、工艺条件及工艺流程等。对该技术的发展趋势进行了展望，并对国内研发工作提出了建议。
