Gas yields in the radiolysis of benzene, toluene styrene and their mixtures

Abstract

The G-values of H 2, CH 4 and C 2H 2 are determined in toluene-benzene and toluene-styrene mixtures. From the results it is concluded that CH 3 radicals generated from toluene are captured both by benzene and styrene but, as expected, the reaction is much more efficient with styrene. A radical precursor of C 2H 2 which could be hexatrienyl is efficiently scavenged by toluene, presumably by H atom transfer. This reaction also accounts for the very low yield of C 2H 2 in pure toluene.
