Abstract: Adipic acid was synthesized by tungstomolybdophosphate acid-catalyzed oxidation of cyclohexanol with 30% hydrogen peroxide in the absence of organic solvent and phase-transfer agent. The effects of amount of catalyst and of 30% H2O2，reaction temperature and time were investigated. Under the optimal conditions，i.e.，molar ratio of cyclohexanone：tungstomolybdophosphate acid：hydrogen peroxide 100∶0.15∶500，reaction temperature 120℃，reaction time 8 h，the isolated yield of adipic acid could reach 82.0%.

摘要： 以自制H3PW6Mo6O40·nH2O为催化剂，在无有机溶剂、相转移催化剂的情况下，用过氧化氢氧化环己醇合成己二酸。探讨了催化剂用量、过氧化氢用量、反应时间、反应温度对反应的影响。在优化条件下，即n(环己醇)∶n(磷钼钨杂多酸)∶n(过氧化氢)=100∶0.15∶500，在120 ℃反应8 h，己二酸的分离收率达82%。
