GLUTARIC ANHYDRIDE pure - Preparation Method
Open Data Verified Data
- Glutaric acid is produced by heating with a dehydrating agent such as acetic anhydride.
- a dicarboxylic acid (succinic acid, Glutaric acid, adipic acid) is mixed by heating, succinic acid and Glutaric acid are directly dehydrated and anhydrided, and a fraction at a certain temperature is taken to obtain Glutaric anhydride.

| use | mainly used for the production and preparation of rubber, plastic, resin, medicine, etc. used for the production of plastic, rubber, resin, medicine, etc. and the preparation of amide. Valeric anhydride is oxidized with hydrogen peroxide to obtain glutaric acid peroxide. Stir and mix 420ml of distilled water with 221.7g of 30% hydrogen peroxide, add 342g of glutaric anhydride, stir vigorously, maintain the reaction at 15 ℃, add 7.6g of hydrogen peroxide, continue to keep the temperature for 1 hour, stand for 24 hours, filter out crystals, wash with water, and dry with an infrared lamp to obtain white powder, peroxidation to diacid, melting point 89-90 ℃ (decomposition starts at 90 ℃). |
| production method | 1. dehydrating glutaric acid with dehydrating agent such as hepatitis B. 2. Heat and mix dicarboxylic acids (succinic acid, glutaric acid, adipic acid) to directly dehydrate succinic acid and glutaric acid, and take a fraction at a certain temperature to obtain glutaric anhydride. |
| spontaneous combustion temperature | 320°C |
