  • Applicaiton:

    1. It is mainly used to produce unsaturated polyester resin, alkyd resin, malathion, 4049 with high efficiency and low toxicity, and long-acting iodoamine. 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 additives, papermaking auxiliaries, plasticizers and tartaric acid, fumaric acid, tetrahydrofuran, etc. It can be used for curing epoxy resin, succinic acid and succinic anhydride in organic synthesis. In the pharmaceutical industry, it is used to manufacture long-acting sulfonamides and other drugs. In the food industry, it is used to make sour agents such as malic acid and tartaric acid.

    2. Reagents for the determination of organic compounds with conjugated double bond. It is also used in synthetic resin, coating, pesticide, medicine, food, lubricant additive and so on.

    3. Used in organic synthesis, synthetic fiber intermediate. It is used as an analytical reagent, such as one for the determination of organic compounds with conjugated double bonds.

    4. Used as curing agent for epoxy resin. It can also be used to graft EVA and PE blends to prepare a new type of hot melt adhesive and improve the adhesion. In organic synthesis, it can be used to produce succinic acid, succinic anhydride, γ - butyrolactone, tetrahydrofuran, succinimide, succinyl chloride, unsaturated polyester resin, dibutyl maleate (Plasticizer), etc. In pesticide industry, it is used to manufacture malathion, maleic hydrazide, fungicide and herbicide. In the pharmaceutical industry, it is used to manufacture long-acting sulfanilamide, aminophylline and other drugs. In the food industry, it is used to make sour agents such as malic acid and tartaric acid. It can also be used as paper sizing agent, lubricating oil pour point depressant, water quality stabilizer, ink additive, fabric softener and surfactant.
