摘　　要：环己烷的催化氧化是重要的工业反应之一,为了寻找更高效廉价的催化剂,研究了仲钼酸铵(APM)对环己烷氧化的催化活性,并着重探讨了酸助剂的种类及添加量对APM催化活性的影响。与硝酸相比,乳酸对环己醇转化为环己酮的过程促进作用更强,且使反应物的有效利用率更高,并由此将APM对目标产物的总TON(turn over number)值由124提高到161。Cyclohexane oxidation is one of the most important industrial reactions. In order to find more efficient and cheap catalysts for this reaction, we studied the catalytic activity of ammonium paramolybdate （APM）. By GC analysis, we focus on the effects of the species and the amount of the acids on the reactivity. Compared with nitric acid, lactic acid is more effective for the oxidation of cyelohexanol to cyclohexanone, and thus improve the TON（ turn over number） value of the target products from 124 to 161. Furthermore, we pro- pose a possible reaction mechanism of this new way for green oxidation of cyclohexane.
