Abstract

Disclosed are processes for the preparation of cyclohexanedicarboxylic acids by the non-catalytic hydrolysis or acidolysis of dialkyl cyclohexanedicarboxylate esters. The processes provide a means for converting dialkyl cyclohexanedicarboxylate esters to cyclohexanedicarboxylic acids without the co-production of solid by-products which present disposal problems.
