Glutaric anhydride is also known as gluconic anhydride, or GA. Glutaric anhydride is a needle, the proportion is 1.429, melting point 41 ~ 56, boiling point 287, soluble in ether, ethanol tetrahydrofuran, etc. After absorbing water, it is diacid. By glutaric nitrile react with hydrochloric acid to rise into glutaric acid and ammonium chloride, pure glutaric acid, was again in 300 ℃ dehydration system of glutaric anhydride.

Mainly for the production and preparation of rubber, plastics, resins, pharmaceuticals, etc. Preparation of plastics, rubber, resins, pharmaceutical and other production and amides used. Valeric anhydride oxidation with hydrogen peroxide may be too oxoglutarate. 420ml of distilled water and the hydrogen peroxide 221.7g30% mixing, then adding glutaric anhydride 342g, with vigorous stirring, the reaction was maintained at 15 ℃, additional 7.6g of hydrogen peroxide incubation was continued for 1 hour, allowed to stand for 24h, filtered off crystals, after washing with water and drying infrared light, into a white powdery peroxy acid, m.p. 89-90 ℃ (90 ℃ begins to decompose).
