Patent ID: 8067650

Claim:
A continuous integrated manufacturing process for the production of trans-1,3,3,3-tetrafluoropropene which consists of the steps: (a) dehydrofluorinating 1,1,1,3,3-pentafluoropropane in a vapor phase reaction, in the absence of an oxygen-containing gas, to produce a product stream comprising cis-1,3,3,3-tetrafluoropropene, trans-1,3,3,3-tetrafluoropropene and hydrogen fluoride; (b) removing the hydrogen fluoride from the product stream of step (a); and (c) recovering trans-1,3,3,3-tetrafluoropropene from the product stream of step (a) or step (b) by distilling the product stream of step (a) or step (b) to isolate and recover the trans-1,3,3,3-tetrafluoropropene therefrom.
