✦ Synopsis

The homogeneous gas-phase decomposition kinetics of methylsilane and methylsilane-d3 have been investigated by the comparative-rate-single-pulse shock-tube technique a t total pressures of 4700 torr in the 1125-1250 K temperature range. Three primary processes occur: CH:$iH3 -CH3SiH + HS (l), CH3SiH3 -CH4 + SiHz (2), and CH3SiH3 -CHa = SiH2 + H2 (3). The high-pressure rate constants for the primary processes in CH3SiH3 obtained by RRKM calculations are log ( k l + k s ) (s-l) = 15.2 -64,780 cal/@ and log kz (s-l) = 14.50 -67,600 f 2800 cal/O. For CH3SiD3 these same rate constants are log k l (s-l) = 14.99 -64,700 call@, log k2 (s-l) = 14.68 -66,700 f 2000 cal/O, and log k:$ (s-l) = 14.3 -64,700 cal/ 0.

The static system pyrolysis of methylsilane ( T -700 K, PT -150 torr), pure and in the presence of ethylene, propylene, and acetylene, has been investigated. It is proposed that in the uninhibited system, the major products (silane and dimethylsilane) are produced by free radical processes, and that
