Description:
Fumaric acid, a carboxylic acid derived from butene, is a colorless
and flammable crystal. It is the simplest unsaturated dicarboxylic
acid. Also known as fumaric acid or fumaric acid. It was first
found in Corydalis yanhusuo. In addition, it also exists in a
variety of mushrooms and fresh beef. Fumaric acid and maleic acid
are geometric isomers of each other. Fumaric acid is transformed
into maleic acid when heated to ******0 ºC. Fumaric acid can also
produce monobasic and binary esters or amides, but it can not
produce monobasic acyl chloride. It reacts with phosphorus
pentachloride or thionyl chloride to form binary acyl chloride.
Trans maleic acid is oxidized by potassium permanganate to form
racemic tartaric acid.

Fumaric acid uses
:
Fumaric acid, as a food sour agent, plays an important role in
bacteriostasis and anti-corrosion. It is used as acidity regulator,
acidifier, anti thermal oxidation assistant, curing accelerator and
spice. Fumaric acid is an intermediate of fine chemicals such as
medicine and optical bleach. In the pharmaceutical industry, it is
used for the production of antidote sodium dimercaptobutyrate and
blood rich iron for the treatment of small red blood cell anemia.
Fumaric acid is also used to produce unsaturated polyester resin
and is also the main raw material for the production of L-aspartic
acid.
