Detailed Product Description

Common name: Trans-Butenedioic Acid

Formula:C4H4O4

Molecular Weight:116.07

CAS No.: 110-17-8

Grade: industrial and Food grade

Description: White odorless powder or crystalline solid particles, with special 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 inether, and very slightly soluble in chloroform. It has no hygroscopicity, and willsublime at 200°C. Boiling point: 290°C (decompose). It will turn tomalefic anhydride at 230°C, and will generate DL-malic acid if boiled withwater.

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 replacemalic acid, citric acid, for its acidity degree is 1.5 times of that of citricacid. Fumaric acid can be used as pharmaceutical intermediate and optical bleachingagent, also used in manufacturing unsaturated polyester resin.
