|Fumaric acid has a prolonged sour taste and a much stronger acidity than citric acid.
Fumaric acid is used to produce unsaturated polyester resin, which is characterized by good chemical corrosion resistance and heat resistance; the copolymer of fumaric acid and ethylene acetate is a good adhesive, and the copolymer with styrene is the raw material for manufacturing FRP. It is an intermediate of fine chemicals such as medicine and optical bleaching agent. It is used in the production of antidote dimercaptosuccinic acid in the pharmaceutical industry. The fumaric acid is neutralized with sodium carbonate to obtain sodium fumarate ([17013-01-3]), and then replaced with ferrous sulfate to obtain iron fumarate. It is a drug rich in blood iron used for the treatment of small red blood cell anemia.
Fumaric acid is also known as fumaric acid, whose chemical name is fumaric acid. It is an important organic basic chemical raw material and fine chemical product, which is widely used in coating, resin, medicine, plasticizer, and other fields. Industrial-grade fumaric acid is used to produce unsaturated resin and alkyd resin, and as raw material for producing electrophoretic paint.
