Mainly for the preparation of succinic anhydride five heterocyclic compound.
Also for the preparation of the alkyd resin (alkyd resin produced by the acid has good flex, flexibility and water resistance.), Paints, dyes (diphenyl succinate dye intermediates, and aminoanthracene after generating anthraquinone dyes quinone reaction.), food flavoring agent (acid can also be used as an acidulant wine, feed, candy and other seasonings.), photographic materials.
The pharmaceutical industry can use it to produce sulfa drugs, vitamin A, vitamin B and other anticonvulsants, loose phlegm, diuretics and drugs to stop bleeding. Chemical reagents used for the standard method of alkali reagents, buffers, GC comparison samples. Also useful as a lubricant material and surfactant.
Used for synthesis of organic materials. Purpose: succinic acid has been identified as the U.S. FDA GRAS (generally recognized as safe), which makes it possible for multiple purposes. It is the citric acid cycle (TCA) intermediates, but also one of succinic acid fermentation product of anaerobic metabolism is widely used in medicine, pesticides, dyes, perfumes, paints, food, plastics and other industries, as well as compounds C4 Platform , synthesis of some important chemical products, such as butanediol, tetrahydrofuran, γ-butyrolactone, n-methylpyrrolidone (NMD), 2 – pyrrolidone, market demand world Over 276000 t / a in addition, succinic acid also. used to synthesize biologically degradable polymers such as polybutylene succinate (PBS) and a polyamide, which makes the high market demand succinic 27000000t / a.
Market: Currently, sales of industrial-grade succinic acid over 15,000 t, largely through the petrochemical law, from butane through maleic anhydride production. Only food market succinic acid is produced by fermentation. The new fermentation process to make succinic acid
Succinate
Succinate
Sales price down to $ 2.20 / kg (annual 5000t); year when production was 75,000 t, its selling price will be less than $ 0.55 / kg, this price can open a new commercialization of succinic acid chemicals market. U.S. Department of Energy has invested $ 7 million study of succinic acid fermentation for the production of industrial, succinate there are four major markets: the largest market as surfactants, detergents additives and foaming agent; Second Market as ion chelating agent used in the electroplating industry to prevent metal corrosion and pitting; third markets as acidifiers in the food industry, PH conditioner, flavor and antimicrobial agents; fourth market and health-related products, including pharmaceuticals, antibiotics, amino acids and vitamins production. The total of these four markets succinic over four hundred million U.S. dollars per year.
1 succinic acid can inhibit the passive and active cutaneous anaphylaxis, and can reduce animal serum IgE antibody formation
2 of succinic acid on the cobra venom in mice showed a protective effect
