METHOD FOR PRODUCING PERFLUOROSULFONIC ACID HAVING ETHER STRUCTURE AND ITS DERIVATIVE, AND SURFACTANT INCLUDING FLUORINE-CONTAINING ETHER SULFONIC ACID COMPOUND AND ITS DERIVATIVE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing the following: perfluorosulfonic acid (perfluoroalkoxy perfluoroalkyl sulfonic acid) which does not cause isomerization, etc., is capable of producing a compound having an objective structure at a low cost, and has an ether structure; its derivative; and its raw material compound.;SOLUTION: A compound having an objective structure and capable of being safely fluorinated without causing isomerization, etc., is produced at a low cost by adding R_H²OR_H¹SO₂F to hydrofluoric acid to form a concentrated solution (a hydrogen bond complex) and supplying the solution to a liquid phase reaction system using an F₂ gas, or, by adding R_H²OR_H¹SO₂Cl to hydrofluoric acid, to release HCl, and to convert R_H²OR_H¹SO₂Cl into R_H¹OR_H²SO₂F and supplying R_H¹OR_H²SO₂F directly to the liquid phase reaction system using an F₂ gas.;COPYRIGHT: (C)2010,JPO&INPIT
