Abstract: Provided are azeotropic and azeotrope-like compositions of 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf) and 2-chloro-1,1,1,2-tetrafluoropropane (HCFC-244bb). Such azeotropic and azeotrope-like compositions are useful as intermediates in the production of 2,3,3,3-tetrafluoropropene (HFO-1234yf).

Abstract: Provided is a process for purifying an organic feedstock comprising (a) distilling a raw organic feedstock comprising hydrogen fluoride, 2-chloro-1,1,1,2-tetrafluoropropane, and 2-chloro-3,3,3-trifluoropropene to produce a first distillate stream comprising an azeotrope-like composition of 2-chloro-1,1,1,2-tetrafluoropropane, 2-chloro-3,3,3-trifluoropropene, and hydrogen fluoride, and a first bottoms stream rich in hydrogen fluoride; (b) cooling said first distillate stream to produce an intermediate composition comprising an organic layer rich in 2-chloro-1,1,1,2-tetrafluoropropane and 2-chloro-3,3,3-trifluoropropene, and an acid layer rich in hydrogen fluoride; and, optionally but preferably, (c) distilling said organic layer to produce a second distillate stream comprising an azeotrope-like composition of 2-chloro-1,1,1,2-tetrafluoropropane, 2-chloro-3,3,3-trifluoropropene, and hydrogen fluoride, and a second bottoms stream comprising a purified organic feedstock substantially free of hydrogen fluoride.
