Fumaric acid is used in the production of unsaturated polyester resins. This type of resin is characterized by good chemical resistance and heat resistance; the copolymer of fumaric acid and vinyl acetate is a good adhesive. Copolymer with styrene is the raw material for manufacturing FRP. The plasticizer made by fumaric acid is non-toxic and can be used for vinyl acetate latex in contact with food. This product is a fine chemical intermediate such as medicine and optical bleaching agent. It is used in the production of antidote dimercaptosuccinic acid in the pharmaceutical industry. The fumaric acid is neutralized with sodium carbonate to obtain sodium fumarate ( [17013-01-3]), and then replaced with ferrous sulfate to obtain iron fumarate, which is used to treat small red blood cell anemia with iron-rich drugs. This product is used as a food additive-sour agent, used in refreshing drinks, fruit candy, jelly, ice cream, etc., most of which are used in combination with the sour agent citric acid. The monosodium salt made by the reaction of fumaric acid and sodium hydroxide, It is also used as a sour seasoning and as an intermediate for synthetic resin and mordant.
