Title:

METHOD FOR PRODUCING AND SEPARATING FLUORINE-CONTAINING FLUORIDE VINYLSULFONATE OR FLUORINE-CONTAINING VINYLSULFONATE

Document Type and Number:

Japanese Patent JP2022112918

Kind Code:

A

Abstract:

To provide a method for producing a fluorine-containing fluoride vinylsulfonate (3) that is useful as a raw material of a fluorine-based polymer electrolyte as a main component of a diaphragm for a fuel cell, a catalyst binder polymer for a fuel cell and a diaphragm for brine electrolysis with a high yield, or a method for producing a fluorine-containing vinylsulfonate (4) capable of being converted into various fluorine compounds; a method for separating a fluorine-containing fluoride vinylsulfonate (3) and a fluorine-containing vinylsulfonate (4); and a method for reusing a compound using in the separation method.SOLUTION: A method for producing a fluorine-containing fluoride vinylsulfonate (3) or a fluorine-containing vinylsulfonate (4) reacts a fluorine-containing vinyl sulfonic acid anhydride (1) with an alkali metal fluoride (2) at a reaction temperature of 60-100°C.SELECTED DRAWING: None
