Additional_detail: Fumaric acid
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 speical sourness
that is as strong as 1.5 times of
citric acid. It is soluble in
ethanol (5.76g/100g,30℃),
slightly soluble in water
(0.63g/100ml,25℃) and in ether,
and very slightly soluble in
chloroform. It has no
hygroscopicity, and will sublime
at 200℃. Boiling point: 290℃
(decompose). It will turn to
malefic anhydride at 230℃, and
will generate DL-malic acid if
boiled with water.

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.
