Glutaric Anhydride 
Glutaric Anhydride used as curing agent of epoxy resin. Pharmaceutical Intermediate，It is also a polymerization initiator for the production of some synthetic resins and synthetic rubbers.
Glutaric acid and ammonium chloride were obtained by the reaction of glutaronitrile and hydrochloric acid. Glutaric acid was purified and then dehydrated at 300 ℃ to produce glutaric anhydride
