Fluorinated saturated and olefinic compounds formed by contacting HCC-230fa with HF in step (1) can include, for example, 1-chloro-1,3,3,3-tetrafluoro-1-propene (HCFC-1224zb), 1,1-dichloro-1,3,3,3-tetrafluoropropane (HCFC-234fb), 1,3-dichloro-1,1,3,3-tetrafluoropropane (HCFC-234fa), 1,1-dichloro-3,3,3-trifluoro-1-propene (HCFC-1223za), 1,1,1-trichloro-3,3,3-trifluoropropane (HCFC-233fb), 1,1,3-trichloro-1,3,3-trifluoropropane (HCFC-233fa), 1,1,3-trichloro-3,3-difluoro-1-propene (HCFC-1222za), 3,3,3-trichloro-1,1-difluoro-1-propene (HCFC-1222zc), 1,1,1,3-tetrachloro-3,3-difluoropropane (HCFC-232fb), 1,1,3,3-tetrachloro-1,3-difluoropropane (HCFC-232fa), 1,1,3,3-tetrachloro-3-fluoro-1-propene (HCFC-1221za), 1,3,3,3-tetrachloro-1-fluoro-1-propene (HCFC-1221zb) and 1,1,1,3,3-pentachloro-3-fluoropropane (HCFC-231fa). In addition, small amounts of 1-chloro-1,1,3,3,3-pentafluoropropane (HCFC-235fa), and 1,1,3,3,3-pentafluoro-1-propene (HFC-1225zc) may also be formed, particularly if a catalyst is present. When CCl3CH2CCl3 is used as the starting material, small amounts of CCl3CH=CCl2 (another possible starting material) can be formed in addition to fluorinated compounds. The step (1) reaction is controlled to provide a fluorinated product which includes no more than about 40 mole percent HFC-236fa.
