RADIOLYSIS OF METHYLCYCLOHEXANE. I. LIQUID PHASE
The gamma-radiolysis of liquid methylcyclohexane was studied over the dose range 0.40 to 35.0 x 10/sup 19/ ev/ml. The initial 100 ev yields of the products are: H/sub 2/, 4.80 plus or minus 0.07; (1-methylcyclohexene + methylenecyclohexane), 2.65 plus or minus 0.15; (3-methylcyclohexene + 4- methylcyclohexene), 0.83 plus or minus O 0.10; open chain heptene , 0.33 plus or minus 0.02; open chain heptene' , 0.31 plus or minus 0.04; bi- methylcyclohexyl, 0.75 plus or minus 0.05; methylcyclohexylheptene, 0.l3 plus or minus 0.02. Methylcyclohexyl -methylcyclohexene wais a secondary product, resulting mainly from reaction of methylenecyclohexane and partly from reaction of 1-methylcyclohexene. Vaiues of the ratios of the olefin yields to the dimer'' yields in the cyclohexane and methylcyclohexane systems were compared with values of disproportionation to combination ratios for moderately bulky alkyl radicals in the gas phase. It was concluded that the major portions of the olefins and dimers in the radiolytic systems were formed by the disproportionation and combination of radicals. A steric hindrance effect probably has a small influence on the rate of the combination reaction. It was illustrated that a polymerizati"n reaction occurs, involving the olefinic products, although the polymer could not be characterized. The relative significance of the polymerization reaction increases with decreasing dose rate.
