Maleic Anhydride consumption
Product Overview
Maleic anhydride (CAS No.: 108-31-6) is a key unsaturated organic anhydride with a chemical formula of C₄H₂O₃. It appears as white or light yellow crystalline flakes with a pungent odor, high reactivity, and excellent compatibility with various monomers and chemicals. As a versatile organic chemical raw material, it is widely used in polymers, coatings, pharmaceuticals, agriculture, and oil & gas industries, providing stable performance and reliable quality for industrial production.
Applications & Uses
Maleic Anhydride's versatility drives its use across numerous industries:
Unsaturated Polyester Resins (UPR)
Primary Application: Over 50% of global MA production is used in UPRs.
End-Use Products: Fiberglass-reinforced plastics, tanks, pipes, automotive parts, boat hulls, and construction panels.
Copolymers
Lubricant Oil Additives: Used as a component in copolymers that act as viscosity index improvers and dispersants.
Surface Coatings: A raw material for alkyd resins used in high-quality industrial paints and coatings.
Agricultural Chemicals
Intermediate: Used in the synthesis of pesticides, herbicides (e.g., Malathion), and plant growth regulators.
Food Additives
Fumaric and Malic Acid: Maleic Anhydride is a precursor to these non-toxic acids, used as acidulants in beverages and food products.
Other Applications
Paper Sizing: Used in the production of alkyl ketene dimer (AKD), a common sizing agent for paper.
Tetrahydrofuran (THF) / Gamma-Butyrolactone (GBL): Cis-Butenedioic Anhydride is an important route for producing these valuable solvents.
Succinic Anhydride: Readily converted to succinic anhydride for various chemical syntheses.
