Kinetic studies of the reaction of hydroxyl radicals with trichloroethylene and tetrachloroethylene

Rate coefficients are reported for the gas-phase reaction of the hydroxyl radical (OH) with C 2HCl 3 ( k 1) and C 2Cl 4 ( k 2) over an extended temperature range at 740±10 Torr in a He bath gas. These absolute rate measurements were accomplished using a laser photolysis/laser-induced fluorescence (L...

Zusammenfassung:Rate coefficients are reported for the gas-phase reaction of the hydroxyl radical (OH) with C 2HCl 3 ( k 1) and C 2Cl 4 ( k 2) over an extended temperature range at 740±10 Torr in a He bath gas. These absolute rate measurements were accomplished using a laser photolysis/laser-induced fluorescence (LP/LIF) technique under slow flow conditions. The simple Arrhenius equation adequately describes the low temperature data for k 1 (
