Novel polyfluorosulfonate salts

Abstract

Abstract COMPOUNDS OF THE FORMULA Q-O-R-SO2M WHEREIN M REPRESENTS AN ALKALI METAL ATOM; R REPRESENTS A DIVALENT RADICAL SUCH THAT THE OXYGEN AND SULPHUR ATOMS ARE LINKED BY A CHAIN OF THREE OR FORU CARBON ATOMS WHICH ARE JOINED TO EACH OTHER BY SINGLE BONDS OR BY BONDS FORMING PART OF AN AROMATIC RING AND EACH OF WHOSE REMAINING VALENCIES IS SATISIFIED BY A HYDROGEN OR HALOGEN ATOM, AN ALKOXY RADICAL OR AN UNSUBSTITUTED, ALKOXY-SUBSTITUTED OR HALOGEN SUBSTITUTED HYDROCARBYL RADICAL OR BY A DIVALENT UNSUBSTITUTED, ALKOXY-SUBSTITUTED OR HALOGEN-SUBSTITUTED HYDROCARBLENE RADICAL WHICH ALSO SATISFIES ANOTHER OF THE SAID REMAINING VALENCIES; AND Q REPRESENTS A SATURATED RADICAL CONSISTING OF CARBON, HYDROGEN AND FLUORINE ATOMS AND CONTAINING AT LEAST THREE FLUORINE ATOMS IN WHICH THE CARBON ATOM LINKED TO THE OXYGEN ATOM IS NOT LINKED TO A FLUORINE ATOM, MAY BE PREPARED BY REACTING AN ALKALI METAL SALT OF A POLYFLUORO ALCOHOL WITH AN APPROPRIATE SULTONE. THESE COMPOUNDS ARE USEFUL AS SURFACE ACTIVE AGENTS, AS INTERMEDIATES IN THE PREPARATION OF TEXTILE TREATING AGENTS AND IN THE PREPARATION OF MODIFIERS FOR PLASTIC MATERIALS.
