Kinetics of the Reaction of Hydrogen Atoms with 1,I-Difluoroethylene

Abstract

Hydrogen atoms generated in a Wood-Bonhoeflcr discharge were reacted with 1,1-difluoroethylene. The products of the reaction were: HF, C2H4, C2H6, C2H2, CH4, C3H6, n-C4H10, ( 3H8 and C2H3F. With the exception of HF, n-C4H10 and C3H8, al! were quantitatively studied over the temperature range 303-603 K. The kinetics and mechanism of the H atom4-CF2CH2 reaction have been studied in detail. The rate constants have been calculated for each step of the mechanism for three temperatures allowing determination of activation energies. The calculation of the rate constants and testing of the mechanism were accomplished by numerical integration of the simultaneous differential equations for each species involved in the reaction.
