Descripción
A). Description:
Fumaric Acid occurs as white agranules or as a crystalline powder. It is soluble in alcohol, slightly soluble in water and in ether, and very slightly soluble in chloroform.
B). Chemical Name: Trans-butenedioicacid; Allomaleic Acid; 1, 2-Ethylenedicarboxylic Acid c). Molecular Formula: C4H4O4
Formula Weight: 116.07
CAS No.: 110-17-8
C) Usage:
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.
D) Package:
25kg net in plastic woven bag lined with PE bag, 18 MT/20′FCL (with pallet) or 20MT/20′FCL (without pallet).
E) Storge:
Store in a cool, dry, well-ventilated area away from incompatible substances.
B. Fumaric Acid-CWS
The solubility of cold aqueous fusion fumaric acid is more than 65% 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.
