Appearance: White crystal
Specification: trans-butenedioic acid has bacteriostatic and antiseptic function. It can be used as acidulant, acidity regulator, acidifier. Properties: White odorless powder or, with speical sourness that is as strong as 1.5 times of citric acid. It is soluble in ethanol (5.76g/100g,30°c), slightly soluble in water (0.63g/100ml,25°c) and in ether, and very slightly soluble in chloroform. It has no hygroscopicity, and will sublime at 200°c. Boiling point: 290°c (decompose). It will turn to maleic anhydride at 230°c, and will generate DL-malic acid if boiled with water. Usage:Trans-butenedioic 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. White crystal, flammable, fruity sour odor.This product is mainly used as raw materials to produce polyester resin and alkyd,or to produce bonding agent when polymerized with vinyl acetate. It can also be used as acidulant for medicine material,food and beverage.The annual production capacity of our company for fumaric acid is 2000 ton per year,which is in the leading position among the same industries in China.The product is exported to Japan, Korea and other countries and regions.
