Cooxidation of Hydrocarbons in Liquid Phase. VI. Reactivities of Hydrocarbons and Peroxy Radicals

Abstract

Abstract Cooxidation of all the combinations of two hydrocarbons among styrene, α-methylstyrene, tetralin and cumene was studied at 70° C in the presence of azobisisobutyronitrile as a thermal initiator. The reactivity ratios for each binary mixture were determined by several appropriate methods. The relative reactivities of styrene, α-methylstyrene, tetralin and cumene toward the peroxy radicals were approximately in the ratio 15 : 10 : 5 : 1. It was also concluded that the secondary peroxy radicals were more reactive than the tertiary peroxy radicals and that the polymeric peroxy radicals were more reactive than the normal alkylperoxy radicals.
