Kinetics of the reaction of OH radical with ethylfluoroacetate, ethyl 4,4,4-trifluorobutyrate, and butylfluoroacetate.

Kinetics of the gas-phase reactions of •OH radicals with a series of fluoroesters were studied for the first time at 298 ± 3 K and atmospheric pressure. Relative rate coefficients were determined by in situ FTIR spectroscopy in nitrogen and GC-FID in air to monitor the decay of reactants and references. The following coefficient values (in 10 cm/(molecule•sec)) were obtained for ethyl fluoroacetate (EFA), ethyl 4,4,4-trifluorobutyrate (ETB), and butyl fluoroacetate (BFA), respectively: k (EFA + OH) = 1.

Rate coefficients of the gas-phase reactions of Cl atoms with a series of fluorinated diketones (FDKs): CFC(O)CHC(O)CH (TFP), CFC(O)CHC(O)CHCH (TFH) and CFC(O)CHC(O)CH(CH) (TFMH), have been measured at (298 ± 2) K and under atmospheric pressure. The experiments were performed using the relative-rate method with a GC-FID detection system. From different determinations and references used, the following rate coefficients were obtained (in cm/(molecule·sec)): k(TFP + Cl) = (1.
