Abstract: Aspects of the invention relate to systems and processes for recovering R1233zd in purified form from compositions additionally comprising hydrogen fluoride. In accordance with one aspect, the invention provides a process that includes separating a feed stream comprised of hydrogen fluoride and R1233zd using azeotropic distillation in a first distillation column to produce a first distillate stream comprised of hydrogen fluoride and R1233zd and a first bottoms stream consisting essentially of hydrogen fluoride. The first distillation column is operated at a first pressure. The process further includes separating the first distillate stream using azeotropic distillation in a second distillation column to produce a second distillate stream comprised of hydrogen fluoride and R1233zd and a second bottoms stream consisting essentially of R1233zd. The second distillation column is operated at a second pressure that may be different than the first pressure of the first distillation column.

Abstract: A method of separating a composition containing at least one organofluorine compound from at least one inorganic compound by contacts the composition with a semipermeable membrane. Other methods separate a organofluorine compound from a composition containing at least one other organofluorine compound or chlorocarbon. Methods also include isolating a single organofluorine compound from a composition comprising a mixture of organofluorine compounds, chlorocarbons, and/or inorganic compounds.

Abstract: A method for removing a contaminant from a hydrochlorofluoroolefin (such as trans-1,1,1-trifluoro-3-chloro-2-propene (1233zd(E))) includes extracting a chlorofluorocarbon (such as trichlorofluoromethane (R11)) from a mixture comprising the hydrochlorofluoroolefin and the chlorofluorocarbon using extractive distillation in the presence of an extractive solvent comprising a chlorinated compound to form a purified hydrochlorofluoroolefin. This separation method provides for removal of a contaminant, such as R11, from a hydrochlorofluoroolefin, such as 1232zd(E), which are not separable by conventional distillation methods. The method may employ a process utilizing two distillation columns, for example, a first extractive distillation column and a second solvent recovery column, which allows for recycle of the extractive solvent to the first extractive distillation column.

Abstract: The present invention provides a process for the manufacture of trans 1-chloro-3,3,3-trifluoropropene (E-1233zd). The first step of the process comprises the fluorination of 1,1,3,3-tetrachlororopropene (1230za, CCh?CH—CHCh) and/or 1,1,1,3,3-pentaachloropropane (240fa) to a mixture of cis 1233zd (Z-1233zd) and trans 1233zd (E-1233zd). The second step of the process comprises a separation of the mixture formed in the first step to isolate cis 1233zd (Z-1233zd) from the mixture. The third step of the process comprises isomerization of cis 1233zd (Z-1233zd) to trans 1233zd (E-1233zd).
