%X Hydrogen abstraction from   (CH3),S and CH3COCH3 by CH3 radicals    CH3+CH3SCH3 &#8594; CH4+CH3SCH2    CH3 + CH3COCH3 &#8594; CH4 + CH3COCH2  has been studied in the temperature range 120-245º. The rate constants, based on the value of 1013.34cm3 mol-l s-1 for the recombination of CH3 radicals, are given by (k in cm3 mol-1 s-1, E in kJ mol-1, R = 0.008314 kJ K-1 mol-1):     logk1 = (11.62 ± 0.08) ? (38.35 ± 0.68)/2.303RT    logk3 = (11.61 ± 0.05) ? (40.48 ± 0.46)/2.303RT  Combination of the results for (1) with thermochemical data gives a calculated value of     Logk-1 = (11.8 -63.7/2.303RT    for the rate constant of the reverse reaction. The results for CH3+(CH3)2S are compared with all of the available data for hydrogen abstraction by free radicals from both sulphur-containing compounds, and molecules of the type (CH3)xM.
