发明名称 Method of preparing alkaline difluoromethane sulfonates
摘要 A method of preparing alkaline difluoromethane sulfonates by reacting an alkali-metal sulfite of the formula M2SO3, in which M represents an alkali-metal of column 1 of the Periodic Table of the Elements, with at least an equimolecular quantity of chlorodifluoromethane in aqueous medium, in an autoclave under autogenous pressure, characterized by the fact that the reaction is carried out in the presence of at least one strong alkali-metal base of the formula M'OH, in which M' represents an alkali-metal of column 1 of the Periodic Table of the Elements.
