CHARACTER

ethylene carbonate, chemical formula C3H4O3, is a colorless transparent liquid with good chemical stability and thermal stability. Ethylene carbonate is an important organic chemical raw material and intermediate, which is widely used in lithium battery electrolyte, medicine, pesticide and synthetic fiber. In the lithium battery industry, ethylene carbonate, as an important part of the electrolyte, can significantly improve the cycle performance and safety of the battery; in the pharmaceutical field, it is the key raw material for the synthesis of a variety of drugs; in addition, ethylene carbonate is also used in the manufacture of pesticides and synthetic fibers to improve product performance and quality. As a multifunctional organic compound, ethylene carbonate is widely used in many industrial fields and is one of the indispensable raw materials in modern chemical industry.

APPLICATIONS

(1) Ethylene carbonate is an organic solvent with excellent performance, which can dissolve a variety of polymers, such as polyacrylonitrile, polyvinyl chloride, etc., and is an important additive in the processing of these polymers.

(2) As an organic intermediate, ethylene carbonate can replace ethylene oxide for dioxylation reaction, and it is also the main raw material for the production of dimethyl carbonate by transesterification method, which is widely used in the field of chemical synthesis.

(3) Ethylene carbonate can also be used as a raw material for the synthesis of furazolidone, which is a broad-spectrum antimicrobial agent with important applications in the pharmaceutical and veterinary fields.

(4) Ethylene carbonate is also used in lithium battery electrolyte, as an excellent solvent, which helps to improve the performance and safety of lithium batteries.

(5) In the textile industry, ethylene carbonate can be used as a fiber finishing agent and other processing aids, which can improve the feel and gloss of the fiber and improve the quality of textiles.
