CL INITIATED DECOMPOSITION MECHANISMS OF BROMOCHLOROMETHANE

An FTIR study on Cl initiated oxidation of bromochloromethane in air w as carried out in order to evaluate its degradation products in the tr oposphere. Carbon monoxide, carbon dioxide, and hydrogen chloride were mainly produced, while formyl chloride and bromochlorocarbonyl were d etected as minor Kinetic studies indicated that both formyl chloride a nd formyl bromide were produced from CHClBrO, which was a main interme diate of bromochloromethane decomposition, and that the branching rati o for formyl chloride formation from it was estimated to be ca. 0.7.
