Cyclohexane dicarboxylic acid anhydride. A dicarboxylic acid is an organic compound containing two carboxyl functional groups COOH. The general molecular formula for dicarboxylic acids can be written as HO 2 CRCO 2 H where R can be aliphatic or aromatic. In general dicarboxylic acids show similar chemical behavior and reactivity to monocarboxylic acidsDicarboxylic acids are also used in the preparation of copolymers.
