essential information

Maleic anhydride, abbreviated as maleic anhydride, commonly known as dehydrated malic anhydride, has a melting point of 52.8 ℃. It is a colorless needle shaped or sheet-like crystal in the orthorhombic crystal system, which dissolves in ethanol and forms esters. It has a pungent odor.

application area 

1. Used as a raw material for the production of 1,4-butanediol, gamma butyrolactone, tetrahydrofuran, succinic acid, unsaturated polyester resin, alkyd resin, etc., and also used in medicine and pesticides.
2. Serve as a collector in metal beneficiation.
3. Used for organic synthesis and also as a synthetic fiber intermediate.
4. Maleic anhydride is an important unsaturated organic anhydride raw material used in pesticide production to synthesize the intermediate of organophosphorus insecticide malathion, diethyl succinate, the intermediate of pyridazine, 1-phenyl-3,6-dihydroxypyridazine, as well as the intermediate of pyrethroid insecticides such as pyrethroids, fungicides, and fungicides. In addition, it is also used in the production of unsaturated polyester resins, ink additives, papermaking additives, coatings, and the pharmaceutical and food industries.
5. It is mainly used as a raw material for the production of unsaturated polyester resin, alkyd resin, pesticide malathion, high-efficiency and low toxicity pesticide 4049, and long-acting iodine amine. It is also a coating, maleic anhydride, maleic anhydride styrene copolymer. It is also an organic chemical raw material for the production of ink additives, papermaking additives, plasticizers, and tartaric acid, fumaric acid, tetrahydrofuran, etc.
6. Maleic anhydride (108-31-6) is a commonly used and important basic organic chemical raw material. Mainly used for synthesizing unsaturated polyester resin, it is a raw material for manufacturing automotive components, ships, corrosion-resistant chemical equipment, and daily necessities. Maleic anhydride (108-31-6) is also an important intermediate in the production of lubricants, coatings, pesticides, fumaric acid, copolymers, food additives, and other additives.

Packaging, Storage, Transportation, and Safety

1. Transportation precautions: The packaging should be intact and the loading should be secure during shipment. During transportation, it is necessary to ensure that the container does not leak, collapse, fall, or be damaged. It is strictly prohibited to mix and transport with oxidants, reducing agents, acids, edible chemicals, etc. During transportation, it should be protected from direct sunlight, rain, and high temperatures;

2. Storage precautions: Store in a cool, dry, and well ventilated warehouse. Stay away from sources of fire and heat. Keep the container sealed. It should be stored separately from oxidants, reducing agents, acids, and edible chemicals, and avoid mixing storage. Equip with corresponding types and quantities of fire-fighting equipment. The storage area should be equipped with suitable materials to contain leaked materials;

3. Packaging precautions: Plastic bags or double-layer kraft paper bags with full or medium opening steel drums on the outside; Plastic bags or double-layer kraft paper bags with fiberboard drums, plywood drums, or cardboard drums; Plastic drum outside the plastic bag (solid); Plastic bucket (liquid).
