Process for producing pentafluoroethane and tetrafluorochloroethane |
| abstract |
The invention relates to a process for producing HFC-125 and/or HCFC-124 from PCE. The process involves a first reaction step of fluorinating PCE in the presence of catalyst in a liquid phase to form HCFC-123 and/or HCFC-122 and a second reaction step of fluorinating HCFC-123 and/or HCFC-122 in the presence of catalyst in a vapor phase to form HFC-125 and/or HCFC-124. This process gives an improved yield of objective products, the catalyst remains effective for a long period, and the reaction temperature can be controlled without difficulty. |
