    摘要: A process for the production of fluorinated alkanes by contacting a feed stream containing a fluorinated olefin and a reducing agent, preferably with a first amount of catalyst to produce a fluorinated alkane, at a first conversion level, wherein a first effluent stream contains unreacted fluorinated olefin and reducing agent; and contacting the first effluent stream under conditions effective to produce a higher level of conversion than said conversion level.

    摘要: Disclosed is a process for the manufacture of HFO-1234yf from TCP in three integrated steps that include hydrofluorination of TCP (tetrachloropropene) to HCFC-1233xf in the vapor phase followed by hydrofluorination of HCFC-1233xf to HCFC-244bb in the liquid phase which is then followed by dehydrochlorination in liquid or vapor phase to produce HFO-1234yf. The vapor phase hydrofluorination is carried out at a higher pressure than the liquid phase hydrofluorination, thereby eliminating the need for compression and/or intermediate recovery. Also, any HCl generated from this reaction is fed to the liquid phase hydrofluorination section to promote agitation and mixing. This results in a more economical process from an initial capital and operating cost versus conducting the 3-steps sequentially.

    摘要: The invention provides a process for the manufacture of fluoropropanes, and more particularly, the manufacture of 1,1,1,3,3,3-hexafluoropropane (HFC-236fa) and 1,1,1,2,3,3,3-heptafluoropropane (HFC-227ea). The process utilizes 3-carbon by-products, i.e. waste material, from other commercial processes as raw material. The process also avoids the use of hexafluoropropane (HFP) as a reactant for making HFC-227ea, and is able to convert any three-carbon hydrocarbon (HC), hydrochlorofluorocarbon (HCFC), chlorofluorocarbon (CFC) compound or any halogenated propanes and produce high valued three-carbon hydrofluorocarbons (HFCs) at significantly lower cost than current commercial processes.
