Abstract: Disclosed is a process for preparing cis-1,1,1,4,4,4-hexafluorobutene comprising the steps of (a) reacting CCl4 with a compound having the formula CF3CX?CXH, where each X is independently halogen or hydrogen, to form a compound having the formula CF3CXClCXHCCl3; (b) fluorinating the compound formed in step (a) to form a compound having the formula CF3CXHCXHCF3; (c) converting the compound formed in step (b) by a reaction selected from the group consisting of dehydrohalogenation, dehalogenation and both reactions, to form a compound having the formula CF3C?CCF3; and (d) catalytically reducing the compound formed in step (c) with hydrogen to form the compound having the formula:

Abstract: The present invention provides a simple three step process for the production of 1,3,3,3-tetrafluoropropene (HFO-1234ze). In the first step, carbon tetrachloride is added to vinyl fluoride to afford the compound CCl3CH2CHClF (HCFC-241fb). HCFC-241fb is then fluorinated with anhydrous HF to afford CF3CH2CHClF (HCFC-244fa) in the second step. Dehydrochlorination of HCFC-244fa, in the third step, affords the desired product, CF3CH?CHF (HFO-1234ze). Following similar chemistry, vinyl chloride may be used in place of vinyl fluoride.

Abstract: The present invention describes a process for making CF3CH?CHF (HFO-1234ze). The process involves the addition of carbon tetrachloride (CCl4) to 1,2-dichloroethylene to form CCl3CHClCHCl2. The compound CCl3CHClCHCl2 thus can then either be treated with HF to produce CF3CHClCHClF as the main product, or it can be converted to CCl2?CHCHCl2 (1230za) by dechlorination. CCl2?CHCHCl2 can be treated with HF such that the main product obtained is CF3CHClCHClF. CF3CH?CHCl may be produced as a by-product, but upon treatment with HF, it affords the compound CF3CHClCHClF. The desired compound, CF3CH?CHF (HFO-1234ze), is obtained as a trans/cis mixture by dehydrochlorination of CF3CH2CHClF or by dechlorination of CF3CHClCHClF.

Abstract: Disclosed is a process for the preparation of fluorine-containing olefins comprising contacting a chlorofluoroalkane with hydrogen in the presence of a catalyst at a temperature sufficient to cause replacement of the chlorine substituents of the chlorofluoroalkane with hydrogen to produce a fluorine-containing olefin. Also disclosed are catalyst compositions for the hydrodechlorination of chlorofluoroalkanes comprising copper metal deposited on a support, and comprising palladium deposited on calcium fluoride, poisoned with lead and reducing the in the presence or absence of a dehydrochlorination catalyst under conditions effective to form a product stream comprising cis-1,1,1,4,4,4-hexafluoro-2-butene (HFO-1336).

Abstract: The present invention provides a method for the preparation of suitable chlorofluorocarbon and hydrochlorofluorocarbon materials or chlorofluorocarbon and hydrochlorofluorocarbon alkene and alkyne intermediates which serve as useful feedstock for fluorination and reduction to cis-1,1,1,4,4,4-hexafluoro-2-butene. Also presented is a continuous process for the production of cis-1,1,1,4,4,4-hexafluoro-2-butene from the alkene and alkyne intermediates.

Abstract: Disclosed is a process for making hexafluoro-2-butyne comprising the steps of: (a) providing a composition comprising CF3CX?CXCF3, where X=halogen; and (b) treating CF3CX?CXCF3 with a dehalogenation catalyst in the presence of a halogen acceptor compound Y, where Y is not hydrogen. The halogen acceptor compound Y is a material capable of being halogenated, preferably a compound having a multiple bond, such as an alkyne, alkene, allene, or carbon monoxide. Another suitable material capable of being halogenated is a cyclopropane. A catalyst effectively transfers halogen from CF3CX?CXCF3 to the halogen acceptor compound. Since Y is not hydrogen, the formation of CF3CX?CHCF3 is greatly reduced or eliminated.
