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

The G-values of H2, CH4 and C2H2 are determined in toluene-benzene and toluene-styrene mixtures. From the results it is concluded that CH3 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 C2H2 which could be hexatrienyl is efficiently scavenged by toluene, presumably by H atom transfer. This reaction also accounts for the very low yield of C2H2 in pure toluene.
