Abstract
Rate constants for the reaction of OH radicals with CHFCl2 and CH3Cl have been determined over the temperature range 298–423 °K using a flash photolysis–resonance fluorescence technique. The Arrhenius expressions obtained were k1(CHFCl2) =1.75×10−12e−(2490±300)/RT cm 3 molecule−1 sec−1, k1(CH3Cl) =4.1×10−12 e−(2700±300)/RT cm3 molecule−1 sec−1. In addition, the rate constant for the reaction of OH radicals with CH2Cl2 was determined to be k1(CH2Cl2) = (1.45±0.20) ×10−13 cm3 molecule−1 sec−1 at 298.5 °K. These rate constants are in good agreement with literature values.
