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.
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.
