Abstract

There is provided a method for preparing oligomers and co-oligomers of highly fluorinated sulfinic acids and salts thereof.

Description

technical field [0001] The present invention relates to highly fluorinated sulfinic acid oligomers and co-oligomers and their salts. The present invention relates to a process for the preparation of highly fluorinated sulfinic acid oligomers and co-oligomers and their salts. Background technique [0002] Fluorinated sulfinates have utility in fluoropolymer and hydrocarbon processing. Methods for the synthesis of fluorinated sulfinates and their use as intermediates have been extensively reported in the literature. For example, perfluoroalkane sulfinates can be prepared from the corresponding perfluoroalkane halides by dehalogenation and sulfination reactions, such as C.M.Hu, F.L.Quing and W.Y.Huang, JOrgChem (Journal of Organic Chemistry), 1991, 2801-2804 and reported in W.Y. Huang, Journal of Fluorine Chemistry, 58, 1992, 1-8. Several reagent systems have been developed for use in this reaction, such as sulfite plus oxidizing agent, hydroxymethanesulfinate, thiourea diox...
