실험 절차

The process for producing tetrafluoropropenes of the present invention comprises contacting a raw material composition comprising 1-chloro-2,3,3,3-tetrafluoropropane (HCFC-244eb) and dichloropentafluoropropane including 1,1-dichloro-2,2,3,3,3-pentafluoropropane (HCFC-225ca) and at least one of its isomers, with an alkali aqueous solution in the presence of a phase-transfer catalyst, to produce 1,1-dichloro-2,3,3,3-tetrafluoropropene (CFO-1214ya) from the 1,1-dichloro-2,2,3,3,3-pentafluoropropane (HCFC-225ca), and to produce 2,3,3,3-tetrafluoropropene 1234yf) from the 1-chloro-2,3,3,3-tetrafluoropropane (HCFC-244eb).
