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.
