摘要： 本文研究了在二苯甲酰甲烷氧钒VO(dbm)2存在下,环己基过氧化氢(CHHP)的分解动力学,实验表明:CHHP催化分解接近等摩尔生成环己醇和环己酮,产物环己醇对CHHP的分解有明显阻化作用,当(VO(dbm)2)<2.5×10-4M/1、温度在50—70℃之间时,CHHP催化分解的初始速率Ro服从如下关系式:Ro=kK[VO(dbm)2]o[CHHP]o/(1+K[CHHP]o)表观活化能Ea=53.7KJ/M,k=1.9×108exp(-53.7×103/RT)秒-1。

Abstract: The kinetics of decomposition of cyclohcxyl hydroperoxide (CHHP) in benzene catalyzed by vanadyl dlbenzoylmethane VO(dbm)2 has been studied. It is found that the products of decomposition of CHHPare cyclohexanol and cyclohexanone, which are produced in about equimolar quantities, and that one of the products cyclohexanol obviously inhibits decomposition of CHHP.
