Abstract

Relative rate techniques were used to study the title reactions in 930–1200 mbar of N~2~ diluent. The reaction rate coefficients measured in the present work are summarized by the expressions k(Cl + CH~2~F~2~) = 1.19 × 10^−17^ T^2^ exp(−1023/T) cm^3^ molecule^−1^ s^−1^ (253–553 K), k(Cl + CH~3~CCl~3~) = 2.41 × 10^−12^ exp(−1630/T) cm^3^ molecule^−1^ s^−1^ (253–313 K), and k(Cl + CF~3~CFH~2~) = 1.27 × 10^−12^ exp(−2019/T) cm^3^ molecule^−1^ s^−1^ (253–313 K). Results are discussed with respect to the literature data. © 2009 Wiley Periodicals, Inc. Int J Chem Kinet 41: 401–406, 2009
