Abstract: A process for selective oxidation of dimethyl-1,1′-biphenyl to form methyl-1,1′-biphenyl mono-carboxylic acid(s), comprising contacting a solution of dimethyl-1,1′-biphenyl in acetic acid solvent in the presence of a Co(II) acetate catalyst and air, and optionally adding a co-solvent, or adding sodium or potassium acetate, and oxidizing the dimethyl-1,1′-biphenyl under time and temperature conditions sufficient to form one or more methyl-1,1′-biphenyl mono-carboxylic acid(s). The mono-carboxylic acids are advantageously isolated and esterified to form biphenyl mono-esters for use as plasticizers.
