A process for producing an isomerized benzene carboxylic acid salt by treating a mixture of an aromatic material, water, and a water soluble reagent comprising a Group Ia or IIa metal with oxygen under conditions sufficient to convert at least a portion of the aromatic material to a benzene carboxylic acid salt of the metal; isomerizing the benzene carboxylic acid salt by heating without converting the benzene carboxylic acid salt to a benzene carboxylic acid salt of a different Group Ia or IIa metal prior to isomerizing; and recovering the benzene carboxylic acid salt. Another embodiment further comprises converting the isomerized benzene carboxylic acid salt to isomerized benzene carboxylic acid; regenerating the reagent; recovering the isomerized benzene carboxylic acid; and recycling the reagent thusly regenerated to supply a portion of the reagent required for producing the benzene carboxylic acid salt. In one embodiment the water soluble reagent is potassium carbonate, or potassium bicarbonate or mixtures thereof. In one embodiment a benzene carboxylic acid salt is produced from carbonaceous material having a high degree of aromaticity.
