Patent ID: 7161049

Claim:
A process for purifying a hydrofluoropropane comprising: contacting a first mixture comprising a hydrofluoropropane, an olefinic impurity and a saturated chlorinated impurity with hydrogen and hydrogen fluoride concurrently in the presence of a bifunctional catalyst, whereby said olefinic impurity is converted to at least one first saturated derivative selected from the group consisting of a saturated hydrogenated derivative of said olefinic impurity and a saturated hydrofluorinated derivative of said olefinic impurity, and whereby said saturated chlorinated impurity is converted to at least one second saturated derivative selected from the group consisting of a saturated hydrodechlorinated derivative of said saturated chlorinated impurity and a saturated fluorinated derivative of said saturated chlorinated impurity, to form a second mixture comprising hydrofluoropropane substantially free of said olefinic impurity and said saturated chlorinated impurity, and recovering said second mixture.
