    Abstract: In this method, RH2ORH1SO2F 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. Alternatively, RH2ORH1SO2Cl is added to hydrofluoric acid so as no be converted into RH1ORH2SO2F by disc barging HCl, and the RH1ORH2SO2F 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.

  • Publication number: 20120302787
    Abstract: A process for producing a perfluorobutanesulfonic acid salt (PFBS salt) is provided. By the process, the yield is improved and PFOS salt content is reduced. Electrochemical fluorination is conducted in a reaction solution comprising anhydrous hydrogen fluoride to generate perfluorobutanesulfonyl fluoride, and the fluoride is hydrolyzed to produce a perfluorobutanesulfonic acid salt. The process for producing a perfluorobutanesulfonic acid salt includes: a step in which liquid phase components generated in the electrochemical fluorination cell are withdrawn and a first a perfluorobutanesulfonic acid salt fraction is prepared therefrom; and a step in which gaseous phase components discharged from the electrochemical fluorination cell are collected and a second perfluorobutanesulfonic acid salt fraction is prepared therefrom.

  • Publication number: 20020029978
    Abstract: The present invention is directed to a method and apparatus for plating a surface of a semiconductor workpiece (wafer, flat panel, magnetic films, etc.) using a liquid conductor that makes contact with the outer surface of the workpiece. The liquid conductor is stored in a reservoir and pump through an inlet channel to the liquid chamber. The liquid conductor is injected into a liquid chamber such that the liquid conductor makes contact with the outer surface of the workpiece. An inflatable tube is also provided to prevent the liquid conductor from reaching the back face of the workpiece. A plating solution can be applied to the front face of the workpiece where a retaining ring/seal further prevents the plating solution and the liquid conductor from making contact with each other. In an alternative embodiment, electrical contacts may be formed using an inflatable tube that has either been coated with a conductive material or contains a conductive object.
