Information @ a Glance

General

  • Succinic acid is a dicarboxylic acid. Succinate plays a biochemical role in the citric acid cycle.

  • Succinic acid is a colourless crystalline solid with a melting point of 185 -187 C and soluble in water; slightly dissolved in ethanol, ether, acetone and glycerine; not dissolved in benzene, carbon sulfide, carbon tetrachloride and oil ether.

  • Succinic Acid occurs as colorless to white crystals or as a white crystalline powder. It is odorless and has a characteristic acid taste.

Process

  • The BDSA(Biologically Derived Succinic Acid) process produces succinic acid by fermenting glucose sugar from corn, separating and purifying the acid, and catalytically processing it as a platform chemical to produce 1,4-butanediol (BDO) and related products, tetrahydrofuran and γ-butyrolactone; n-methyl pyrrolidinone (NMP) and 2-pyrrolidinone; or other chemicals that are used to make a wide assortment of products.

  • The original method employed by Pasteur for the separation of succinic acid from other acids produced during fermentation consisted in extracting the calcium salts with a mixture of alcohol and ether.

  • Succinic acid is a dicarboxylic acid which has attracted great interest as a green feed stock for the manufacture of synthetic resins, biodegradable polymers and chemical intermediates. It can be produced as an intermediate of tricarboxylic acid cycle (TCA) and also as one of the fermentation products of anaerobic metabolism.

Application

  • Succinic acid is valued for its derivative chemicals, which are used in producing food and pharmaceutical products, surfactants and detergents, plastics, clothing fibers, biodegradable solvents, and other products.

  • Succinic acid has been used in many industrial applications, and has been used as a surfactant, a detergent extender, a foaming agent, and an ion chelator. It has also been used as a food additive, a flavoring agent, and a supplement to pharmaceuticals, antibiotics, and vitamins.

  • Succinic acid concentrations are monitored in the manufacture of numerous foodstuffs and beverages, including wine, soy sauce, soy bean flour, fruit juice and dairy products (e.g. cheese).

Market

  • The production volume of succinic acid in China accounts for 25~30% the global succinic acid output. Each year more than 1,500 tonnes of China’s succinic acid was exported overseas.

  • Succinic acid is comprehensively used in China and plays an important role in Chinese economy, including chemical, food, pharmaceutical and agricultural industries.

  • The export volume of succinic acid is fluctuating these years, however, it is still be very bright for it to develop. On one hand, it is because of the development of production method, and on the other hand, it is for the constant and increasing market demand from the downstream products. It is believed that the future of succinic acid will be profitable. It is definitely necessary to grow up with China’s succinic acid industry.
