Yields of y-resorcylic acid afforded by various modifications of the Kolbe-Schmitt reaction have been explored and methods of separating the acid from the accompanying @-isomer have been studied. Selective elution of the acids from a column of an anion-exchange resin in the chloride form with solutions of hydrochloric acid in water or aqueous alcohol effects complete separation.A process for the partial conversion of Pinto y-resorcylic acid is reported.
