1,145,964. Polyfluorosulphonate salts. ALLIED CHEMICAL CORP. 23 March, 1967 [24 March, 1966], No. 13794/67. Heading C2C. Novel compounds of the formula wherein M represents an alkali metal atom; R is a divalent radical such that the O and S atoms are linked by three or four carbons which are joined to each other by single bonds or by bonds forming part of an aromatic ring system and each of whose remaining valencies is satisfied by H, halogen, alkoxy or a monovalent, divalent or polyvalent unsubstituted, alkoxy- or halogen substituted hydrocarbon radical, which satisfies one, two or more of the said remaining valencies; and Q represents a radical consisting of carbon, hydrogen and at least three fluorine atoms in which the carbon atom linked to the oxygen is not linked to a fluorine atom; are made by reacting the appropriate salt of a polyfluoroalcohol: Q-OM with the appropriate sultone of formula R includes alicyclic and polyalicyclic radicals, Q may be, for example, CY(Y 1 )(Y 2 ) wherein Y, Y 1 and Y 2 are H, CH 3 or CF 3 (CF 2 ) p (CH 2 )mwherein m and p are 0-15, at least one of Y, Y 1 and Y 2 being CF 3 (CF 2 ) p (CH 2 )m-. |
