Preparation of chlorosyringols and chloropyrogallols - Components of pulp bleaching effluents

The preparation and properties of chlorosyringols and chloropyrogallols, components of pulp bleaching effluents, and their acetates are given. The compounds are obtained mainly by direct chlorination of both phenols or of syringol acetate with various chlorinating reagents. 5-Chloropyrogallol and 4,5-dichloropyrogallol were the products of demethylation of 5-chloro-3-methoxycatechol acetate and 4,5-dichloro-3-methoxycatechol acetate, respectively. The acetates of all ten chloro compounds were separated by gas chromatography. Electron impact mass spectra and 1H and 13C NMR data for the acetates are given.
