ABSTRACT:
Carbon-carbon coupled self-condensation products obtained by the oxidative coupling of alkylphenols or 1-naphthols are prepared by contacting an aqueous mixture of an alkyl phenol or 1-naphthol with oxygen in the presence of sufficient alkaline material to sustain a pH in the range of 5-10 during the oxidative coupling reaction and a catalyst system comprising a cupric, cobaltous, manganous or chromic chelate of a beta- or gamma- diketone or keto ester.
The mixture may optionally contain a surfactant.
