What is Maleic anhydride?

• With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Maleic anhydride   which has developed particularly rapidly in recent years. Do you know about Maleic anhydride?
• The official answer：Rhombohedral colorless needle-like or flaky crystals. Dissolved in water to produce maleic acid. Dissolves in ethanol and produces esters. Irritation Data Skin-Rabbit 500 mg/24 hours Mild; Eyes-Rabbit 1%/2 min Severe Explosive hazard characteristics Explosive mixed with air Flammability hazard characteristics Flammable; fire releases pungent irritating fumes.

What’s the application of Maleic anhydride?

• Used as a raw material for the production of 1,4-butanediol, γ-butyrolactone, tetrahydrofuran, succinic acid, unsaturated polyester resin, alkyd resin, etc. Also used for pharmaceutical and pesticide purposes maleic anhydride, also known as maleic anhydride, maleic anhydride, anhydrous maleic anhydride, is an important unsaturated organic anhydride basic raw material, in the production of pesticides used in the synthesis of organophosphorus insecticide malathion intermediates maleic diethyl, pyridazine sulfide, In addition, it is also used in the production of unsaturated polyester resin, ink auxiliaries, paper auxiliaries, coatings and pharmaceutical industry, food industry, etc. Uses are mainly used in the production of unsaturated polyester resin, alkyd resin, pesticide malathion, high efficiency and low toxicity pesticide 4049, long-acting iodine amine raw materials. It is also used as a raw material for the production of coatings, maleic rosin, polymaleic anhydride and maleic anhydride-styrene copolymer. It is also the organic chemical raw material for the production of ink auxiliary, paper auxiliary, plasticizer, and tartaric acid, fumaric acid, tetrahydrofuran, etc. Use for organic synthesis, also used as synthetic fiber intermediates use metal beneficiation as a trapping agent.
