ABSTRACT:
A starting material comprising 1,2,3,3,3-pentafluoropropene is contacted with an aluminum chlorofluoride (AlClxF3-x) catalyst to obtain a final product wherein the Z/E ratio of 1,2,3,3,3-pentafluoropropene is either increased or decreased relative to the Z/E ratio of 1,2,3,3,3-pentafluoropropene in said starting material.
