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 ₂F ₂) = 1.19×10 ^-17 T ² exp(-1023/T ) cm ³ molecule ^-1 s ^-1 (253- 553 K), k(Cl+CH ₃CCl ₃) = 2.41×10 ^-12 exp(-1630/T ) cm ³ molecule ^-1 s ^-1 (253-313 K), and k(Cl+CF ₃CFH 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.
