Preparation of 1,1,1,2-tetrafluorodichloroethane

摘要

This invention provides for a process for the preparation of 1,1,1,2-tetrafluorodichloroethane (FC-114a) by reacting CF2=CFCl in a polar aprotic solvent with a source of fluoride ion selected from at least one alkali metal fluoride and/or at least one tetraalkylammonium fluoride and with a source of chlorine selected from at least one of CCl4, CCl3CCl3, and CCl3CCl2CCl3 at a temperature from about 25 DEG C. to about 150 DEG C.
