Abstract

Alkylphenols were effectively treated with horseradish peroxidase at pH 7.0 and 30 °C in the presence of H₂O₂ and poly(ethylene glycol) irrespective of the relative position or isomeric form of the alkyl chains. Water-insoluble oligomer precipitates were readily filtered out after enzymatic treatment, and transparent and colorless solutions were obtained for all p- and m-alkylphenols used.
