Bio-based succinic acid (SA)

Molecular formula: C₄H₆O₄

Molecular weight: 118.09

Characteristics: Colorless crystallization, relative density of 1.572 (25/4 C), melting point of 188 C, decompose at 235 C, sublimate under the decompression and distillation, soluble in water, slightly soluble in ethanol and ether.

Application: Widely used in medicine, spices, food preservatives, condiments, food additives, surface active agents and so on. It is widely used in the production of degradable plastics PBS, PBST, PBSA, clothing biological fibers, polyurethane, polyether and other polyester products.

Advantages: Compared with the production process of Petrochemical synthetic method, succinic acid by microbial fermentation is purely natural, pollution-free, and food grade with no reprocessing.It is biodegradable and uses renewable plant resources as raw material to reduce the pollution of chemical synthesis process to the environment.

Succinic acid is a new generation of chemical products developed in the twentieth century. After years of development, it has been widely used in the following fields:

1. The main raw materials for producing sodium glutamate, sodium succinate, food preservatives, condiments, spices and other food additives.

2. The necessary raw materials for composing degradable plastics PBS, PBST, PBSA.

3. It is used as the main raw material for producing polymer materials such as succimide and nylon 54.

4.The main raw material for producing clothing biological fiber materials.

5. Using as auxiliary materials for the production of surfactants.

6. Using as auxiliary materials for the production of polyurethane, polyether and other polyester products.
