Maleic anhydride (maleic anhydride, cis-ethylene-1,2-dicarboxylic anhydride, 2,5-furandione) is an organic compound with high reactivity, soluble in water and organic solvents.
Maleic anhydride (maleic anhydride, cis-ethylene-1,2-dicarboxylic anhydride, 2,5-furandione) is an organic compound with high reactivity, soluble in water and organic solvents.
Maleic anhydride is used in the preparation of unsaturated polyester resins, for the synthesis of fumaric, malic and succinic acids, in the production of vinyl copolymers.
Maleic anhydride is a raw material in the production of hardeners of epoxy resins, food additives, acts as an additive to lubricating oils.
Maleic anhydride can be used in paintwork materials to reduce their drying time and improve quality.
Maleic anhydride is a colorless or white solid substance in the form of briquettes or pungent crystals. Maleic anhydride must meet the following requirements:
