Preparation and properties of chlorinated syringic acids, acetosyringones, acetoguaiacones and methoxy-p-hydroquinones components of pulp bleaching effluents

A range of chlorinated phenols which serve as standards for compounds occurring in effluents from the bleaching of wood pulps with chlorine-containing reagents has been prepared. The chlorinated phenols include chlorosyringic acids, chloroacetosyringones, chloroacetoguaiacones, 5-chloro-2-methoxy-p-hydroquinone and chloro-2,6-dimethoxy-p-hydroquinones. With the exception of the ring-chlorinated acetoguaiacones which were prepared by reaction of chlorovanillin acetates with diazomethane, the compounds were obtained by direct chlorination of appropriate phenols or their acetates. Gas chromatographic and mass spectrometric data for the acetylated phenols are given.

Characterization of high molecular mass fractions of receiving waters and sediments of a pulp mill by CuO-oxidation and HPLC

High molecular mass fractions were separated by ultrafiltration from water samples collected at four sampling stations downstream and one upstream of a kraft pulp mill. These fractions and three sediment samples containing high molecular mass organic compound were degraded by alkaline cupric oxide oxidation. Lignin and humic compounds in fractions were characterized analyzing their oxidation products by reversed phase HPLC and photodiode array detection. -from Authors
