Influence of solid compounds of vanadium on the decomposition of organic peroxides
The authors studied the influence of the oxides of V/sub 2/O/sub 3/, VO/sub 2/, and V/sub 2/O/sub 5/, as well as vanadium nitride VN, on the rate of decomposition of benzoyl peroxide (I) and cumene hydroperoxide (II) in bromobenzene medium. These peroxide compounds are widely used for the initiation of radical reactions. The rate of decomposition of a nonperoxide initiator, azoisbutyrodinitrile (III), in the presence of the same vanadium compounds was measured for comparison. The vanadium oxides studied are shown to catalytically accelerate the radical decomposition of benzoyl peroxide by a factor of 1.7-2.8 and greatly (by a factor of 600-6000) accelerate the decomposition of cumene hydroperoxide, adsorbed on the surface of the solid oxides.
