摘要: A method for producing 1,1,1,2-tetrafluoropropene and/or 1,1,1,2,3-pentafluoropropene using a single set of four unit operations, the operations being (1) hydrogenation starting material comprising hexafluoropropene and optionally recycled 1,1,1,2,3-pentafluoropropene; (2) separation desired intermediate hydrofluoroalkane, such as 1,1,1,2,3,3-hexafluoropropane 1,1,1,2,3-pentafluoropropane; (3) dehydrofluorination hydrofluoroalkane to produce 1,1,1,2,3-pentafluoropropene, followed by another isolate product and, optionally, recycle 1,1,1,2,3-pentafluoropropene.
