Fumaric acid is an important organic chemical raw material, an intermediate of fine chemical products, and an important derivative of maleic anhydride. It is widely used in food, coatings, resins and plasticizers. In the food industry, fumaric acid is used as a sour agent, which can be used in refreshing drinks, Western wine, cold drinks, concentrated fruit juices, canned fruits, pickled vegetables, ice cream. It is an acidic substance used as a gas producing agent for solid drinks, with good bubble persistence and fine product organization.

Application:

1 Use as a mordant;

2 Used in the manufacture of unsaturated polyester resin, pesticides, sour agents and amino acids;

3 As a sour agent, mostly used with citric acid. Can be used for raw wet products and fruit juice drinks, the maximum usage of 0.6g/kg; Can also be used for carbonated beverages, the maximum use of 0.3g/kg.

4 Fumaric acid is used in the production of unsaturated polyester resin, which is characterized by good chemical corrosion resistance and heat resistance; The copolymer of fumaric acid and vinyl acetate is a good adhesive, and the copolymer of styrene is the raw material for the manufacture of glass steel. The plasticizer made of fumaric acid is non-toxic and can be used for vinyl acetate latex in contact with food. The product is a fine chemical intermediate such as pharmaceutical and optical bleach, used in the pharmaceutical industry for the production of the antidote dimercaptosuccinic acid, fumaric acid is neutralized with sodium carbonate, that is, sodium fumaric acid ([17013-01-3]), and then replaced with ferrous sulfate to obtain iron fumaric acid, which is used to treat small red blood cell anemia. The product as a food additive - acid agent, used in cooling drinks, fruit drops, jelly, ice cream, etc., mostly with acid agent citric acid, fumaric acid and sodium hydroxide reaction made of single sodium salt, also used as sour condiments, but also used as synthetic resin, mordant intermediates;

5. Food sour agent, which plays an important role in bacteriostasis and antisepsis; Acidity regulator, acidifier, anti-thermal oxidation agent, salting promoter, spice. When used as acid substance of gas producing agent of solid beverage, the bubbles are durable and delicate; Fine chemical intermediates such as pharmaceutical and optical bleach. It is used for the production of the antidotes sodium dimercaptosuccinate and the drugs for the treatment of small red blood cell anemia. It is also used to produce unsaturated polyester resin.

6 Standard lye. Thorium is isolated from cerium, lanthanum, praseodymium and rubidium. Synthetic resin. A mordant. An antioxidant.
