Structure of Glutaric anhydride (CAS NO.108-55-4):

Product Category of Glutaric anhydride (CAS NO.108-55-4): Pharmaceutical Intermediates;Anhydride Monomers;Carbonyl Compounds;Carboxylic Acid Anhydrides

Uses

Glutaric anhydride(108-55-4) is mainly used in the production of rubber, plastics, resins, medicines, etc.

Production

1. With the dehydrating agent, such asacetic anhydride, heating the glutaric acid to dehydrate it and obtain glutaric anhydride(108-55-4).
2. Heating mixture of binary carboxylic acid (succinic acid, glutaric acid, adipic acid) to dehydrate succinic acid and glutaric acid, then take some of the distillate under a certain temperature to get glutaric anhydride(108-55-4) .
