Ethylene carbonate (EC) is a new type of chemical material. It is an organic solvent with excellent properties and can dissolve many kinds of polymers. In addition, it can be used as an organic intermediate in dioxylation reaction instead of ethylene oxide, and it 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. It can also be used as an active intermediate in the production of lubricating oil and grease, and is a good solvent for polyacrylonitrile and polyvinyl chloride. It can be used as a spinning liquid on textile. It can also be directly used as a solvent to remove acid gas and used as an additive to concrete.It used in medicine as an ingredient or raw material in a pharmaceutical production; It can also be used as a stabilizer for plastic foaming agent and synthetic lubricating oil. In the battery industry, it can be used as an excellent solvent for lithium battery electrolyte.
