Haloethers are expected to be an acceptable alternative to decrease the harmful effects of chlorofluorocarbons (CFCs) and their derivates in the atmosphere. The relative rate technique has been used to determine the rate constants of the reactions of Cl atoms with 2-chloro-1,1,2-trifluoroethyl-methyl-ether (CH3OCF2CHFCl) and 2-chloro-1,1,2-trifluoroethyl-difluoromethyl-ether (CHF2OCF2CHFCl). Experiments were carried out at 296 ± 2 K and atmospheric pressure using nitrogen or synthetic air as bath gases. The decay rates of the organic species were measured relative to those of 1,2-dichloroethane, dichloromethane and 1,1,
