N2 - Rate constants for the reactions of OH radicals with CH3CHF2 and CHC12CF3 have been determined overthe temperature range 295-388 K and a total pressure of 1 atm. The OH rate data were obtained using the absolute rate technique of pulse radiolysis combined with kinetic spectroscopy. The data can be fit to the Arrhenius expressions: kOH+HFC-152a=3.9 × 10-12 exp[(-1370±260)/T] cm3 molecule-1s-1 and kOH+HCF-123=1.1 × 10-12 × exp[(-940±200/T] cm3 molecule-1s-1. The results are compared to the available literature data and discussed in terms of reactivity trends and in the light of the important role CH3CHF2 and CHCl2CF3 play as alternatives to the fully halogenated chlorofluorocarbons.
