METHOD FOR THE MANUFACTURE OF FLUORINATED ETHYLENE CARBONATES

摘要

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.
