Description :

Overview of Maleic Anhydride

Maleic Anhydride is a key organic chemical intermediate widely used in resin manufacturing, polymers, coatings, lubricants, and industrial chemical synthesis. Chemically, the maleic anhydride formula is C₂H₂(CO)₂O or C₄H₂O₃, derived from maleic acid through dehydration. It is an important cyclic anhydride with high industrial relevance.

From a molecular perspective, the maleic anhydride structure consists of a five-membered cyclic anhydride ring with a carbon–carbon double bond, giving it high reactivity toward polymerisation and esterification reactions. Maleic Anhydride appears as a white crystalline solid or flakes with a sharp, pungent odour. The maleic anhydride melting point is approximately 52–54 °C, and it readily sublimes under certain conditions. It is identified in industrial documentation by the maleic anhydride CAS number 108-31-6.

Due to its strong reactivity and versatility, maleic anhydride uses are predominantly industrial.
