Succinic anhydride, with chemical formula C4H4O3, is an important raw material for medicine, dye, paint, and is the important component of drugs and chemical agents, also can be used for Stomach ketone and Succinylsulfathiazole, and for synthesis and preparation of widely used in resin.

At present, there are two methods for the preparation of succinic anhydride. The first method is the direct catalytic hydrogenation of maleic anhydride. The research on the production process of maleic anhydride direct catalytic hydrogenation is widely used, especially on the thermodynamic production process; the second method is to directly dehydrate succinic acid. The main advantage of the second methods is that it has less pollution to the environment and does not use benzene solvents, so many domestic and foreign manufacturers have adopted the second method to product succinic anhydride.

The direct heating of succinic acid to more than 300 degrees Celsius, it can be dehydrated to get the succinic anhydride. Under the action of a water loss agent such as concentrated sulfuric acid, succinic anhydride can also be obtained.
