Glutaric anhydride CAS 108-55-4 is also called colloidal anhydride, or GA for short. Glutaric anhydride is needles, specific gravity 1.429, melting point 41～56℃, boiling point 287℃, soluble in ether, ethanol and tetrahydrofuran. After absorbing water, glutaric acid becomes glutaric acid. Glutaric acid and ammonium chloride are purified by the reaction of glutaronitrile and hydrochloric acid to obtain glutaric acid, and then dehydrated at 300°C to obtain glutaric anhydride
