METHOD FOR THE MANUFACTURE OF FLUORINATED ETHYLENE CARBONATES
Difluoroethylene carbonate, trifluoroethylene carbonate and tetrafluoroethylene carbonate are synthesized from dichloroethylene carbonate, trichloroethylene carbonate and tetrachloroethylene carbonate with fluorinating agents, e.g. alkali metal fluorides, antimony fluorides and especially the HF adducts of amines. The fluorinated carbonates are suitable as additives in lithium ion batteries.

MANUFACTURE OF DIFLUOROETHYLENE CARBONATE, TRIFLUOROETHYLENE CARBONATE AND TETRAFLUOROETHYLENE CARBONATE
Difluoroethylene carbonate, trifluoroethylene and tetrafluoroethylene carbonate are produced by the reaction between elemental fluorine and ethylene carbonate or fluorinated ethylene carbonates with a lower degree of fluorination.
