Use of Maleic anhydride

1. Maleic anhydride is used as a raw material for producing 1,4-butanediol, γ-butyrolactone, tetrahydrofuran, succinic acid, unsaturated polyester resin, alkyd resin, etc., and is also used for medicines and pesticides.
2. Maleic anhydride is used in organic synthesis and also as a synthetic fiber intermediate.
3.Maleic anhydride is an important basic raw material for unsaturated organic acid anhydride. It is used in the synthesis of organophosphate insecticide malathion intermediates of maleic acid diethyl ester and pyridazine. 1-phenyl-3,6-dihydroxypyridazine, and pyrethroid insecticide methrin, fungicide, intermediate of captan, in addition, also used in the production of unsaturated polyester resin, ink aid Agents, papermaking auxiliaries, coatings, pharmaceutical industry, food industry, etc.
4. Maleic anhydride is mainly used to produce unsaturated polyester resin, alkyd resin, pesticide malathion, high-efficiency and low-toxic pesticide 4049, long-acting iodine. It is also a coating, a maleic rosin, a polymaleic anhydride, a maleic anhydride-styrene copolymer. It is also an organic chemical raw material for the production of ink auxiliaries, papermaking auxiliaries, plasticizers and tartaric acid, fumaric acid and tetrahydrofuran.
5. Maleic anhydride is a commonly used basic organic chemical raw material. It is the third largest anhydride raw material in the world after acetic anhydride and phthalic anhydride. Its downstream products have considerable development and application prospects. Mainly used in the synthesis of unsaturated polyester resin, it is the raw material for the manufacture of automotive parts, ships, corrosion-resistant chemical equipment and daily necessities. Maleic anhydride is also an important intermediate for the production of lubricant additives, coatings, pesticides, fumaric acid, copolymers, food additives. The hydrogenated derivatives thereof are succinic anhydride, 1.4-butanediol, r-J lactone and tetrahydrofuran.
