The effect of scavengers, pressure, temperature, and added xenon on the vapor-phase radiolysis of acetone-d/sub 6/ and acetone-acetone-d/sub 6/ mixtures was investigated. Most of the results can be explained on the basis of free radical reactions similar to those occurring in the photolysis of acetone-d/sub 6/ . Values for the ratio of rate constants k/sub 1// k/sub 2//sup 1//< s2>s for the reactions CD/sub 3/ + CD/sub 3/COCD/sub 3/ - CD/sub 4/ + CD/sub 2/COCD/sub 3/ and CD/sub 3/ + CD/sub 3/ - C/sub 2/D/sub 6/ determined from the radiolysis data are in excellent agreement with values based on photolysis experiments, indicating that methane and ethane are formed by the reactions of thermalized methyl radicals. Methane and hydrogen formed in the presence of scavengers are mainly attributed to the occurrence of molecular elimination processes. (auth)
