Abstract:
Disclosed are processes for an isomerization reaction between (E)1-chloro-3,3,3-trifluoropropene and (Z)1-chloro-3,3,3-trifluoropropene. Some of the disclosed processes include the step of contacting a feed stream with a heated surface, where the feed stream includes (E)1-chloro-3,3,3-trifluoropropene, (Z)1-chloro-3,3,3-trifluoropropene or mixtures thereof. The resulting product stream includes (E)1-chloro-3,3,3-trifluoropropene and (Z)1-chloro-3,3,3-trifluoropropene, where the ratio of (E) isomer to (Z) isomer in the product stream is different than the ratio feed stream. The (E) and (Z) isomers in the product stream may be separated from one another.
Abstract:
Disclosed is a process for producing fluorinated organic compounds, including hydrofluoropropenes, which preferably comprises converting at least one compound of Formula (I): C(X)3CF2C(X)3 (I) to at least one compound of Formula (II) CF3CF═CHZ (II) where each X and Z is independently H, F, Cl, I or Br, said process preferably not including any substantial amount of oxygen-containing catalyst in certain embodiments. Preferably Z is H.
Abstract:
The invention provides an economic process for the manufacture of the hydrofluorocarbon 1,1,3,3,3-pentafluoropropene (HFC-1225zc). HFC-1225zc can be made from the dehydrochlorination of 1-chloro-1,1,3,3,3-pentafluoropropane (HCFC-235fa). Alternatively, HFC-1225zc can also be made from the dehydrofluorination of 1,1,1,3,3,3-hexafluoropropane (HFC-236fa). HFC-1225zc) is a compound that has the potential to be used as a low Global Warming Potential refrigerant, blowing agent, aerosol propellant, or solvent.

Abstract:
Disclosed are processes for the production of fluorinated olefins, preferably adapted to commercialization of CF3CF═CH2 (1234yf). Three steps may be used in preferred embodiments in which a feedstock such as CCl2═CClCH2Cl (which may be purchased or synthesized from 1,2,3-trichloropropane) is fluorinated (preferably with HF in gas-phase in the presence of a catalyst) to synthesize a compound such as CF3CCl═CH2, preferably in a 80-96% selectivity. The CF3CCl═CH2 is preferably converted to CF3CFClCH3 (244-isomer) using a SbCl5 as the catalyst which is then transformed selectively to 1234yf, preferably in a gas-phase catalytic reaction using activated carbon as the catalyst. For the first step, a mixture of Cr2O3 and FeCl3/C is preferably used as the catalyst to achieve high selectivity to CF3CCl═CH2 (96%). In the second step, SbCl5/C is preferably used as the selective catalyst for transforming 1233xf to 244-isomer, CF3CFClCH3. The intermediates are preferably isolated and purified by distillation and used in the next step without further purification, preferably to a purity level of greater than about 95%.
