摘要: Phenylacetic acid is obtained by oxidation of phenylacetaldehyde with air or oxygen in the presence of a transition metal derivative e.g. a derivative of Co, Mn, Cr, Cu, Fe. Oxidation may be carried out in an inert hydrocarbon, halogenated hydrocarbon, carboxylic acid or ester, nitrile, tertiary alcohol or ketone or mixtures thereof e.g. tert. butanol and acetic adid. The catalyst may contain additionally derivatives of Group 3a or 4a metals.
