  • Patent number: 8129574
    Abstract: Disclosed is a process and apparatus for the catalytic hydrogenation of fluoroolefins to fluorocarbons where the reaction is carried out in a multi-tube shell and tube reactor. Reactions involving hydrogenation of fluoro-olefins are typically exothermic. In commercial processes where a fluoro-olefin C(n)H(2n?x)F(x) to C(n)H(2n?x+2)F(x) is hydrogenated (e.g. hexafluoropropylene to 236ea, 1225ye to 245eb, and the like), inadequate management or control of heat removal may induce excess hydrogenation, decomposition and hot spots resulting in reduced yields and potential safety issues. In the hydrogenation of fluoro-olefins, it is therefore necessary to control the reaction temperature as precisely as practical to overcome challenges associated with heat management and safety.

  • Patent number: 8084653
    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.
