    摘要: 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.

    摘要: Disclosed is an integrated manufacturing process to co-produce (E)1-chloro-3,3,3-trifluoropropene, (E)1,3,3,3-tetrafluoropropene, and 1,1,1,3,3-pentafluoro-propane starting from a single chlorinated hydrocarbon feed stock, 240fa. The process includes a combined liquid or vapor phase reaction/purification operation which directly produces (E)1-chloro-3,3,3-trifluoropropene (1233zd(E)) from 240fa. In the second liquid phase fluorination reactor 1233zd(E) is contacted with HF in the presence of catalyst to produce 1,1,1,3,3-pentafluoropropane (245fa) with high conversion and selectivity. A third reactor is used for dehydrofluorination of 245fa to produce (E)1,3,3,3-tetrafluoropropene (1234ze(E)) by contacting in the liquid phase with a caustic solution or in the vapor phase using a dehydrofluorination catalyst. This operation may be followed by one or more purification processes to recover the 1234ze(E) product.

    摘要: Disclosed is an integrated process to co-produce trans-1-chloro-3,3,3-trifluoro-propene (1233zd (E)), trans-1,3,3,3-tetrafluoropropene (1234ze (E)), and 1,1,1,3,3-pentafluoropropane (245fa). Overall the co-production is a three-step process. The chemistry involves the steps of: (1) the reaction of 1,1,1,3-tetrachloropropene and/or 1,1,3,3-tetrachloropropene with anhydrous HF in excess in a liquid-phase catalyzed reactor in such a way as to co-produce primarily 1233zd (E) and 244fa (plus by-product HCl); an optionally (2) the 244fa stream can then be used to directly produce any (or all) of the following desired products; (a) the 244fa stream can be dehydrochlorinated to produce the desired second product 1234ze (E); and/or (b) the 244fa stream can be dehydrofluorinated to produce 1233zd (E) if more of that product is desired; and/or (c) the 244fa stream can be further fluorinated to form 245fa.

    摘要: Disclosed are processes for producing halogenated olefins, and preferably tetrafluorinated propene(s), from one or more alkanes having both fluorine substituents and non-fluorine substituents, preferably with a high degree of conversion and selectivity. Preferably the process comprises the use of a catalyzed reaction in which the catalyst is selected from the group consisting of activated carbons, halogentated mono- and di-valent metal oxides, mono- and di-valent Lewis acid metal halides, zero-valent metals, and combinations of these.
