Ethylene carbonate, also correctly referred to as 1,3-dioxolan- 2-one, is a colorless and almost odorless, solid at room temperature connection.

Properties and synthesis

It consists of three carbon and four hydrogen and three oxygen atoms, two of which are as two times the ester group (R -O-CO -O-R ) having two carbon atoms form a five-membered ring. Ethylene is thus to be regarded as cyclic esters of carbonic acid and ethylene glycol, but of ethylene oxide and carbon dioxide ( CO2) produced.

Use

Ethylene carbonate is used in the chemical industry as a raw material for syntheses, and as a solvent at elevated temperatures. It serves as a

  • High-temperature solvent in the spinning of fibers polynitrile
  • Starting material for the synthesis of oxazolidinones, imidazolidones, pyrimidines and purines
  • Component in electrolyte solutions for lithium batteries
