Kinetics and mechanism of the photolysis of CF2ClBr exposed to light with a wavelength of 253.7 nm

Abstract

CF₂ClBr mixed with oxygen was photolyzed using a low pressure mercury lamp, and the kinetics of photolysis was studied. The absorption spectra of the starting material and products of photolysis were recorded in the wavelength range from 200 to 900 nm on an Agilent 8453 spectrophotometer. The concentrations of the main photolysis products at different irradiation times were calculated by the mathematical processing of the absorption spectra. The scheme of CF₂ClBr photolysis was suggested, the model calculations according to this scheme were performed, and the results of simulation were compared with experimental data.
