Ethylene Carbonate

Ethylene Carbonate (EC) is a kind of organic solvent with excellent performance, which can dissolve a variety of polymers. In addition, it can be used as an organic intermediate instead of ethylene oxide for dioxylation reaction, and is the main raw material for the production of dimethyl carbonate by transesterification. It can also be used as raw material for synthesis of furazolidone, sodium silicate slurry, fiber finishing agent, etc. In addition, it is also used in lithium battery electrolyte. Vinyl carbonate can also be used as an active intermediate in the production of lubricating oils and greases.

① Solvent use:

Ethylene Carbonate (EC) is a kind of organic solvent with excellent performance, which can dissolve a variety of polymers. In addition, it can be used as an organic intermediate instead of ethylene oxide for dioxylation reaction, and is the main raw material for the production of dimethyl carbonate by transesterification. It can also be used as raw material for synthesis of furazolidone, sodium silicate slurry, fiber finishing agent, etc. In addition, it is also used in lithium battery electrolyte. Vinyl carbonate can also be used as an active intermediate in the production of lubricating oils and greases.

Ethylene Carbonate (EC) can be a good solvent with Polyacrylonitrile, polyvinyl chloride . used as spinning fluid on the textile; Can also be directly used as a solvent to remove acid gas and concrete additives;

In medicine, components and raw materials used as pharmaceutical ingredients; Can also be used as plastic blowing agent and synthetic lubricating oil stabilizer;


② In battery industry, it can be used as an excellent solvent for lithium battery electrolyte.

Production of electrolyte solvent for lithium battery; Solvent is the main component of electrolyte, accounting for about 80% of its quality in the current market to carbonate solvents, the main varieties are dimethyl carbonate (DMC), ethylene carbonate (EC), diethyl carbonate (DEC), methyl ethyl carbonate (EMC) and so on.
