Title:
METHOD FOR PRODUCING PERFLUOROSULFONIC ACID HAVING ETHER STRUCTURE AND DERIVATIVE THEREOF, AND SURFACTANT CONTAINING FLUORINE-CONTAINING ETHER SULFONIC ACID COMPOUND AND DERIVATIVE THEREOF
Document Type and Number:
WIPO Patent Application WO/2011/040497
Kind Code:
A1
Abstract:
Disclosed is a method wherein RH
2ORH
1SO2F is added to hydrofluoric acid so as to form a thick solution (hydrogen bonded complex) and the solution is directly supplied to a liquid phase reaction system in which an F2 gas is used, or alternatively RH
2ORH
1SO2Cl is added to hydrofluoric acid so as to be converted into RH
1ORH
2SO2F by discharging HCl and the RH
1ORH
2SO2F is directly supplied to a liquid phase reaction system in which an F2 gas is used. Consequently, fluorination can be carried out safely and a compound having an objective structure can be produced at low cost without causing isomerization or the like.
