Maleic anhydride often abbreviated as MA, is an organic compound. It is a colorless crystal, strong stimulating smell, and easy to sublimate. HS code is 29171400. It is mainly obtained from the oxidation of n-butane or butene in benzene or carbon four fractions and is a raw material for the production of unsaturated polyester and organic synthesis.
Douwin is a professional maleic anhydride supplier in China. Founded in 2006, we have rich experience in this area. If you are looking for reliable maleic anhydride manufacturers and maleic anhydride suppliers, don't hesitate to contact us!
Maleic Anhydride should avoid contact with moist air, a strong oxidizer, strong reducing agent, strong acid, strong base, alkali metal, and water. The rhombic system is a colorless acicular or lamellar crystal. It dissolves in ethanol and produces esters. Soluble in ethanol, ether, and other organic solvents, difficult to dissolve in petroleum ether and carbon tetrachloride. Maleic Anhydride reacts with hot water to form maleic acid. It is easy to copolymerize olefins. Homopolymerization is also possible. Maleic Anhydride reacts with a diol to form linear unsaturated polyester and with sulfur trioxide to form sulfonated maleic anhydride.

Maleic anhydride can be used in the production of unsaturated polyester resins, as well as in the production of coatings, drugs, agricultural products, and surfactants. Maleic anhydride is used as a raw material for the production of 1,4-butanediol, γ-butyrolactone, tetrahydrofuran, succinic acid, unsaturated polyester resins, alkyd resins, etc., also used in medicine and pesticides. Mainly used in the production of unsaturated polyester resins, alkyd resins, pesticide malathion, high-efficiency low-toxicity pesticide 4049, and long-acting iodoacetamide. It is also used in coatings, maleic rosin, poly(maleic anhydride), maleic anhydride-styrene copolymers. It is also used in the production of ink additives, paper additives, plasticizers, and organic chemical raw materials such as tartaric acid, fumaric acid, tetrahydrofuran, etc. Used in organic synthesis, also as a synthetic fiber intermediate. As a professional maleic anhydride supplier, Douwin offers high-quality maleic anhydride to meet our customers' application needs.
Studies have found that acute inhalation of maleic anhydride can cause respiratory irritation and eye irritation. However, it has not been classified as a carcinogen. Maleic anhydride dust and vapors are irritating. Inhalation can cause pharyngitis, laryngitis and bronchitis. May be accompanied by abdominal pain. Direct contact between the eyes and the skin is obviously irritating and can cause burns. Chronic effects include chronic conjunctivitis, ulceration of the nasal mucosa and inflammation. It is allergenic and can cause rashes and asthma.
