Application
Maleic Anhydride, also known as maleic anhydride, maleic anhydride, 2,5 Furanedione, etc. . A colorless acicular or lamellar crystal of the RHOMBIC system. Strong pungent odor, soluble in ethanol, ether and Acetone, insoluble in petroleum ether and tetrachloromethane. Reacts with hot water to form MALEIC ACID.
Maleic Anhydride is mainly used in the production of unsaturated polyester resin, alkyd resin, pesticide Malathion, high-efficiency low-toxicity pesticide 4049, long-acting iodomine raw materials. It is also a copolymer monomer of paint, maleic Rosin, polymaleic anhydride and Maleic anhydride-styrene copolymer. It is also an organic chemical raw material for producing ink assistant, paper assistant, plasticizer, tartaric acid, fumaric acid, oxolane and so on.
