VPO复合物催化环己烷亚硝化一步合成ε-己内酰胺
One-step catalytic synthesis of ε-caprolactam from cyclohexane nitrosation catalyzed by transition VPO composites
摘要
Abstract
A series of transition metal-doped M1-M2 vanadium phosphorus oxide ( VPO ) ( M1 = Mn,M2=A1, Mg, Ti ) composite catalysts were prepared by the reduction-dipping method, and were employed to catalyze reaction of cyclohexane with nitrosyl sulfuric acid in the presence of fuming sulfuric acid. ε-caprolactam was directly obtained from such one-step catalytic process. Among them,the Mn-A1-VPO gave the best results with 17.1％ of conversion and 75.6％ of selectivity to ε-caprolactam. A possible mechanism is proposed.关键词
