INVENTION: PROCESS FOR THE PRODUCTION OF CHLOROFLUORINATED SULFONIC ACIDS INVENTORS: RICHARD F. SWEENEY, JAMES O. PETERSON, BERNARD SUKORNICK, MORRIS B. BERENBAUM, HENRY R. NYCHKA AND RICHARD F. EIBECK Chlorofluorinated sulfonic acids may be effectively produced by an oxychlorofluorination process by reacting a gaseous mixture of a starting material selected from a saturated aliphatic sulfur containing compound in which all atoms are selected from C, H, S and O, and corresponding hydrohalogenated compounds in which the halo atoms are selected from chloro and fluoro, or mixtures thereof, an oxygen-containing gas, a chlorinating agent selected from the group consisting of HCl and C12 and mixtures thereof, and HF, in the presence of a Deacon catalyst supported by a stable, inert metal salt carrier.
