CF3CF=CF2 is a potential source of atmospheric trifluoroacetic acid (CF3C(O)OH). The kinetics of the reaction of the simplest Criegee intermediate (CH2OO) with CF3CF=CF2 was studied by using the OH laser-induced fluorescence method. At 10 torr, the rate co-efficients were measured to be (1.45 +/- 0.14)x10(-13), (1.18 +/- 0.11)x10(-13), (1.11 +/- 0.08)x10(-13), and (1.04 +/- 0.08)x10(-13) cm(3)center dot molecule(-1)center dot s(-1) at 283, 298, 308 and 318 K, respectively. The activation energy of (-1.66 +/- 0.21) kcal/mol was derived from the Arrhenius equation. No obvious pressure dependence was observed.
