Disclosed is a process for the manufacture of 1234yf from 1,1,2,3-tetrachloropropene, abbreviated herein as 'TCP,' in three integrated steps: wherein the vapor phase hydrofluorination of TCP in step (a) is carried out at a higher pressure than the liquid phase hydrofluorination of 1233xf; and wherein the HC1 generated during these steps is scrubbed with water to form an acid solution and the organic components are scrubbed with a caustic solution and then dried before further processing.

Methods of making 2,3,3,3-tetrafluoro-2-propene

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.

Processes and systems for the production of phosphorus pentafluoride (PF) through continuous fluorination of phosphorus are provided herein. A phosphorus feed stream and a fluorine feed stream are provided to a reactor, wherein they are reacted in a gas-gas or liquid-gas reaction to produce phosphorus pentafluoride (PF). The phosphorus feed can be derived from white phosphorus or yellow phosphorus, and can be provided to the reactor as a liquid or a vapor. The fluorine can be provided to the reactor as a vapor, and preferably comprises elemental fluorine gas.

Methods and reactor designs for producing phosphorus pentafluoride

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.

Integrated process for fluoro-olefin production

A process for the production of fluorinated olefins, preferably fluorinated propenes, by contacting a feed stream containing a fluorinated olefin and hydrogen with a first amount of catalyst to produce the hydrofluorocarbon, wherein a first exit stream contains unreacted fluorinated olefin and hydrogen; contacting the first exit stream with a second amount of catalyst to produce a hydrofluorocarbon, wherein the second amount of catalyst is preferably greater than the first amount of catalyst; and contacting the hydrofluorocarbon with a catalyst for dehydrohalogenation to produce a product stream of fluorinated olefin.
