    摘要： The present invention relates to processes for reducing the concentration of acidic impurities HF, HCl, HBr, HI, HNO3 and H2SO4 in fluorinated hydrocarbons. The process involves: (i) contacting the fluorinated hydrocarbon with a phosphorous oxyacid salt, and (ii) recovering the fluorinated hydrocarbon having reduced concentration of, or substantially free of, said acidic contaminant, provided that said fluorinated hydrocarbon is not CF3CH2CF3 or CF3CHFCF3.

    摘要： A process is disclosed for purifying a hydrofluoropropane of undesirable C2–C4 olefinic and C1–C4 saturated chlorinated impurities, comprising the steps of: contacting a first mixture of hydrofluoropropane, olefinic impurity and saturated chlorinated impurity with hydrogen and hydrogen fluoride concurrently in the presence of a bifunctional catalyst, for example an alloy of gold and palladium supported on carbon, capable of catalyzing hydrogenation and fluorination. During the contacting step, olefinic impurity is converted to saturated hydrogenated derivative and/or saturated hydrofluorinated derivative, and saturated chlorinated impurity is converted to a saturated hydrodechlorinated derivative and/or saturated fluorinated derivative. The hydrofluoropropane thus formed is substantially free of both the olefinic and saturated chlorinated impurities and may be used as obtained or subject to further purification steps such as distillation to remove the process derivatives (e.g., hydrogenation, hydrodechlorination and hydrofluorination derivatives) from the hydrofluoropropane.

    摘要： A process is disclosed for the catalytic hydrogenolysis of at least one starting material selected from saturated acyclic halofluorocarbons and hydrohalofluorocarbons containing three or four carbon atoms, and from one to five non-fluorine halogens (each non-fluorine halogen being independently chlorine or bromine) wherein all non-fluorine halogen substituents are contained on end carbons. The process involves reacting the starting material with hydrogen at an elevated temperature of about 300.degree. C. or less in the presence of a catalyst containing a catalytically effective amount of palladium supported on carbon to produce a hydrogenolysis product wherein over 80 mole percent of the hydrogenolysis product is a saturated compound having the same distribution of fluorine substituents as the starting material. The carbon support has an ash content of less than about 0.5% by weight.
