Product name: Fumaric acid
Chemical name: Anti butylene diacid
CAS No.: 110-17-8
Molecular formula: C4H4O4
Structural formula:
Molecular weight: 116.07
Physical properties: A colorless or white crystal or powder, soluble in water and ethanol, slightly soluble in cold water, ether, and benzene, easily soluble in hot water. It has no hygroscopicity, and will sublime at 200. Boiling point: 290(decompose). It will turn to maleic anhydride at 230, and will generate DL-malic acid if boiled with water.

Function and Application: Fumaric acid has bacteriostatic and antiseptic function. It can be used as acidulant, acidity regulator, acidifier, thermal-oxidative resist auxiliary, curing accelerant and spice. Widly used in producing various carbonic acid drink, wine, concentrated solid drink, ice cream and other cold foods and drink. It can replace malic acid, citric acid, for its acidity degree is 1.5 times of that of citric acid. Fumaric acid can be used as pharmaceutical intermediate and optical bleaching agent, also used in manufacturing unsaturated polyester resin.
Packing: 25kg/ bag, lined with polythene bag, or 500-1000kg big bag.

Function and Application: The solubility of fumaric acid-CWS is 65% higher than that of original fumaric acid. Its acidity is 2.5 times of that of citric acid. Better emulsibility, stability. It can take the place of malic acid, citric acid, benzoic acid and widely used in cold drink, potables, alcoholic, marmalade, cake, pickle, noodle, bread, etc.
Packing: 25kg/ bag, lined with polythene bag, or 500-1000kg big bag.
