A process for preparation of a fluorinated sulfinate product by reacting a mixture comprising: (1) water; (2) dehalogenating and sulfinating reagent; and (3) fluoroaliphatic sulfonyl fluoride represented by the formula: Rf-[SO2F]n; and (4) at least one of the material selected from the group consisting of: (i) fluorinated surfactant, or (ii) organic cosolvent comprising, as the major component by weight of the organic solvent, alcohol having a boiling point of less than 110 DEG C at 760 torr; by heating the reaction mixture to a temperature between about 50 DEG C and 100 DEG C until the desired product yield is achieved. Also provided is a process of using the fluorinated sulfinate product as an initiation system for a free radical polymerization process, such as that used to prepare fluoropolymers. |
