The mechanism and kinetics of reactions in C/sub 2/H/sub 5/OH vapor during pulsed IR photolysis differ from the pyrolysis case: the main reaction in the first case is molecular dehydration, in the second it is chain dehydrogenation. The reason for the difference is the absence of conditions for chain development during pulsed IR photolysis. The ratio of dehydration to C-C bond rupture during pulsed IR photolysis depends on the radiation energy density, the C/sub 2/H/sub 5/OH vapor pressure, and the composition of the reaction mixture.
