WebNorbornene dicarboxylic anhydride (NDCA) is a chemical compound that belongs to the class of organic compounds known as norbornenes. It is a cyclic compound with a seven-membered ring structure and is composed of two carboxylic acid groups and an anhydride group. NDCA is a white solid at room temperature and has a melting point of around 174°C. WebIt has been reported that tetrahydrophthalic anhydride contains a relatively unreactive double bond.3 It would, therefore, appear to be quite practical to substitute tetrahydrophthalic anhydride for phthalic anhydride in groups (1) and (2) above. The reaction between tetrahydrophthalic anhydride and glycerol yields the following:
