Abstract
AbstractThe kinetics of the gas‐phase reactions of the OH radical with (C2H5O)3PO and (CH3O)2P(S)Cl and of the reactions of NO3 radicals and O3 with (CH3O)2P(S)Cl have been studied at room temperature. Using a relative rate technique, the rate constants determined for the reactions of the OH radical with (C2H5O)3PO and (CH3O)2P(S)Cl at 296 ± 2 K and 740 torr total pressure of air were (5.53 ± 0.35) × 10−11 and (5.96 ± 0.38) × 10−11 cm3 molecule−1 s−1, respectively. Upper limits to the rate constants for the NO3 radical and O3 reactions with (CH3O)2P(S)Cl of <3 × 10−14 cm3 molecule−1 s−1 and <2 × 10−19 cm3 molecule−1 s−1, respectively, were obtained. These data are compared and discussed with previous literature data for organophosphorus compounds.
