Introduction Succinic acid is a colorless crystal; the relative density is 1.572 (25/4ºC), the melting point is 188ºC, and it decomposes at 235ºC; it can be sublimated by distillation under reduced pressure; it is soluble in water, slightly soluble in ethanol, ether and acetone
An important use of succinic acid is to prepare five-membered heterocyclic compounds. For example, succinic acid loses water rapidly when heated to form succinic anhydride, which is a furan ring compound. Succinic anhydride is an important raw material for manufacturing drugs, dyes and alkyd resins. Succinic anhydride and ammonia are heated together to generate succinimide. The hydrogen on the imine group of succinimide can be replaced by bromine to produce N-bromosuccinimide, which is a bromination reagent and mild oxidant for organic synthesis. Succinic acid has antispasmodic, expectorant and diuretic effects in medicine. Diethyl succinate is an important intermediate in organic synthesis. Dibutyl succinate and dioctyl succinate are plasticizers for plastics. Copolymerization of diallyl succinate and 1,3-butadiene can produce artificial rubber.

The main purpose Succinic acid (including salts) can produce sour taste and taste, and can be used in soybean paste, soy sauce, Japanese sake, and seasonings. Sodium succinate is a white crystalline powder with a special taste of shellfish. It is used in the food industry as a flavoring agent, sour agent, buffer, and used in ham, sausage, aquatic products, and flavoring liquids. Succinic acid can be used as preservatives, pH regulators, co-solvents; it can also be used to synthesize antidote, diuretics, tranquilizers, hemostatic agents, synthetic antibiotics, vitamin A, vitamin B, etc. As an ion chelating agent, succinic acid is used to prevent metal corrosion and pitting in the electroplating industry; succinic acid is a good surfactant and a component of detergents, soaps and demulsifiers; succinic acid can It produces depilatory, toothpaste, cleaning agent, and high-efficiency wrinkle-removing cosmetic ester. Succinic acid is also used in lubricants, additives, and elastomers. In textile processing, sizing can be used to prevent shrinkage and improve dyeability. Improve the viscosity and fire resistance of caprolactam.
Mainly used to prepare five heterocyclic compounds such as succinic anhydride.
