Acetone-sensitized and non-sensitized photolyses of tetra-, penta- and hexachlorobenzenes in acetonitrile-water mixtures: photoisomerization and formation of several products including polychlorobiphenyls.

Abstract

rn Photochemical reactions of tetra-, penta-, and hexachlorobenzenes in the presence and absence of acetone as sensitizer at wavelengths 2 285 nm have been studied. The reductive dechlorination is the main photochemical pathway in both sensitized and nonsensitized photolyses. 1,2,4-Trichlorobenzene appears as the main photoproduct of the nonsensitized… (More)
