Rate constants for reactions of OH radicals with (Z)-CF3CCl=CHCl, CHF2CF=CF2, (E)-CF3CH=CHF, (Z)-CF3CH=CHF, CH3CF=CH2, and CH2FCH=CH2

The rate constants for the reaction of OH radicals with six halogenated propenes-(Z)-CF3CCl = CHCl (k(1)), CHF2CF=CF2 (k(2)), (E)-CF3CH=CHF (k(3)), (Z)-CF3CH=CHF (k(4)), CH3CF=CH2 (k(5)), and CH2FCH=CH2 (k(6))-were measured over 250-430 K using the absolute rate method. The Arrhenius expressions for the rate constants were determined as k(1) = (9.30 +/- 0.54) x 10(-13) exp [-(180 +/- 20 )/T], k(2) = (1.43 + 0.04) x 10(-12) exp [(490 +/- 10)/T], k(3) = (4.86 +/- 0.13) x 10(-13) (T/298)(0.7)(27) exp [(110 +/- 10)/T], k(4) = (4.55 +/- 0.12) x 10(-13) (T/298)(0.367) exp [(350 +/- 10)/T], k(5) = (3.22 +/- 0.20) x 10(-12) exp [(490 +/- 20)/T], and k(6) = (2.87 +/- 0.19) x 10(-12) exp [(440 +/- 20)/T] cm(3) molecule(-1) s(-1). Infrared absorption spectra of the halogenated propenes were measured at room temperature. The atmospheric lifetimes, global warming potentials of the halogenated propenes, and ozone depletion potential of (Z)-CF3CCl = CHCl were estimated. The correlation between the reactivity and structure of 44 halogenated alkenes, including the six halogenated propenes, was investigated.
