Abstract: Propylene oxide catalytically dissociates at the silver wire. The first-step product of this reaction is not acetone, but propyl aldehyde. According to the new assumptions suggested, the reaction probability per encounter has been simulated by
p_m=∫~∞_(E_0) 1/(kT) e~(-E/kT)dE/∫~∞_(E_d) 1/(kT)e~(-E/kT)dE
and a satisfactory result has been achieved in both qualitative and quantitative aspects. The energy transfer efficiency at gas-solid surface and the essence of catalytic action have also been reviewed concisely.
