Storage

Firstly, store in a cool, dry and well ventilated warehouse. Keep away from kindling and heat source. Keep container sealed.And then  store them separately from oxidants, reducing agents, acids and edible chemicals, and do not mix them. In addition, provide the fire fighting equipment of corresponding types and quantities . The storage area shall be equipped with appropriate materials to contain the leakage. Avoid exposure to sunlight and moisture. Further, the storage period is 3 months. 2. Packed with lined plastic bag and outer woven bag, with net weight of 25kg and 50kg; And then, they will pack it in iron drums or wooden drums, with a net weight of 50kg. Protect from rain and sun. The storage period is 3 months.

 

Application

Firstly, used to produce 1,4-butanediol γ- Butyrolactone, tetrahydrofuran, succinic acid, unsaturated polyester resin, alkyd resin and other raw materials are also used in medicine and pesticides

And then, used as collector in metal beneficiation

Further, used in organic synthesis and also as an intermediate of synthetic fibers

Secondly, Maleic anhydride, also known as maleic anhydride, maleic anhydride and dehydrated malic anhydride, is an important basic raw material of unsaturated organic anhydride. And then it is used in the production of pesticides to synthesize the intermediate of organic phosphorus pesticide malathion diethyl maleate, the intermediate of pyridazinon 1-phenyl-3,6-dihydroxypyridazine, and the intermediate of pyrethroid insecticide permethrin, fungicide, and captan. In addition, it is also used in the production of unsaturated polyester resin Ink additives, papermaking additives, coatings, pharmaceutical industry, food industry, etc.

Thirdly, it is mainly used as raw material for the production of unsaturated polyester resin, alkyd resin, pesticide malathion, efficient and low toxic pesticide 4049, and long-acting iodamine. It is also a coating, maleic rosin, polymaleic anhydride, maleic anhydride styrene copolymer. It is also an organic chemical raw material for the production of ink auxiliaries, papermaking auxiliaries, plasticizers, tartaric acid, fumaric acid, tetrahydrofuran, etc.

Further, Maleic anhydride (108-31-6) is an important basic organic chemical raw material. It is the third largest raw material of anhydride in the world after acetic anhydride and phthalic anhydride. Its downstream products have quite extensive development and application prospects. Maleic anhydride (108-31-6) is also an important intermediate in the production of lubricant additives, coatings, pesticides, fumaric acid, copolymers, food additives, etc. Its hydrogenation derivatives include succinic anhydride, 1.4-butanediol, r-J lactone and tetrahydrofuran
