Application:

       The product as a food additive - sour agent, used in soft drinks, fruit candy, jelly, ice cream and so on, mostly with citric acid and monosodium salt, fumaric acid and sodium hydroxide reaction made, also used as a sour condiment, is also used as a synthetic resin, mordant intermediates.

Fumaric acid for the production of unsaturated polyester resin, such resins are characterized by good resistance to chemical corrosion, good heat resistance; fumaric acid and vinyl acetate copolymer is a good adhesive, and styrene copolymer is the manufacture of glass fiber reinforced plastic materials, fumaric acid obtained by plasticizers non-toxic, can be used for contact with food vinyl acetate latex. The product is a medical and optical bleaching agent fine chemicals intermediates in the pharmaceutical industry for the antidote two mercaptosuccinic acid production of fumaric acid with sodium carbonate and sodium fumarate, obtain ([17013-01-3]), and then replaced with ferrous sulfate from ferrous fumarate, is used for drug treatment of iron rich blood red blood cell anemia. The product as a food additive - sour agent, used in soft drinks, fruit candy, jelly, ice cream and so on, and most of the citric acid and monosodium salt, fumaric acid and sodium hydroxide reaction made, also used as a sour condiment, is also used as an intermediate in the synthesis of resin, mordant.


Properties:
       A colorless flammable crystal. Slightly soluble in water, ether and acetic acid, soluble in ethanol. Almost insoluble in chloroform. Mainly used for meat products in food, fish products. As the fumaric acid acidity regulator, acidifier, antioxidant additives, curing agent, use of spices. This product has strong buffering effect, in order to keep the solution at about pH3.0, and the antibacterial mildew has an important role, at the same time, it has astringency, is one of the solid acid the strongest acidity, the absorption rate is low, the preservation period helps to extend the powder products, etc. when the fumaric acid into sodium fumarate, water soluble and flavor are better.
