Uses and synthesis of Maleic anhydride powder

Maleic anhydride powder, abbreviated as maleic anhydride, also known as "maleic anhydride", is the acid anhydride of maleic acid.Maleic anhydride CAS 108-31-6 is a colourless or white solid with an acidic odour at room temperature, with the molecular formula C4H2O3.Molecular weight: 98.06.Maleic anhydride Raw Materials is obtained as needle crystals from chloroform or ether. 98.06.Maleic anhydride Raw Materials Needle-like crystals obtained from chloroform or ether.

Applications / Functions of Maleic anhydride powder

• Maleic anhydride powder is used as raw material for the production of 1,4-butanediol, γ-butyrolactone, tetrahydrofuran, succinic acid, unsaturated polyester resin, alkyd resin, etc. It is also used in medicine and pesticide.
• Maleic anhydride CAS 108-31-6 used in organic synthesis, also used as synthetic fibre intermediates
• Used as trapping agent in metal beneficiation.

Physicochemical Property of Maleic anhydride powder

Colourless acicular or lamellar crystals of rhombohedral crystal system. Soluble in water to form maleic acid. Soluble in ethanol and form ester.

Production methodprocess of Maleic anhydride powder

Adopting fixed-bed or boiling-bed reactor, benzene is oxidised to maleic anhydride with air under the action of V-Mo-P catalyst at 365°C. Then water is absorbed to form maleic anhydride. Then the aqueous solution of maleic acid is absorbed with water, and then the maleic anhydride is dehydrated by azeotropic distillation with xylene, and finally the Maleic anhydride Raw Materials are obtained by distillation under reduced pressure.
