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

摘要

In this method, R H 2 OR H 1 S0 2 F is 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 F 2 gas is used. Alternatively, R H 2 OR H 1 SO 2 CL is added to hydrofluoric acid so as to be converted into R H 1 OR H 2 SO 2 F by discharging HCL, and the R H 1 OR H 2 S0 2 F is directly supplied to a liquid phase reaction system in which an F 2 gas is used. Consequently, fluorination can be carried out safely and a compound having an objective structure can be produced at low cost without isomerization or like.
