Abstract

A process for the preparation of phenols by pyrolytic oxidation and decarboxylation in the liquid phase of monocarboxylic acids of the benzene series, or of their salts, esters or anhydrides, in the presence of a copper compound which is present in the dissolved state at the temperature of reaction, with the help of molecular oxygen and water vapor, with separation of the bituminous by-product that has been produced during this procedure, characterized in that this bituminous by-product, mixed with an aromatic hydrocarbon, and/or substituted aromatic hydrocarbon, which contains in the molecule a condensed, unsaturated system of hydrocarbon rings, together with an extraction liquid in which the carboxylic acid can be dissolved.
