MANUFACTURING METHOD FOR DIHALOPHOSPHATE ALKALI METAL SALT, AND MANUFACTURING METHOD FOR DIFLUOROPHOSPHATE ALKALI METAL SALT

摘要

[Problem] To provided a method for manufacturing a dihalophosphate alkali metal salt, and a method for manufacturing a difluorophosphate alkali metal salt, said methods being extremely simple and very efficient. [Solution] In this method for manufacturing a dihalophosphate alkali metal salt, a dihalophosphate alkali metal salt represented by MPO₂X₂ (wherein M is an alkali metal atom, and X is a halogen atom other than fluorine) is generated by reacting an alkali metal hydroxide represented by MOH (wherein M is as previously defined) and a halogenated phosphoryl represented by POX₃ (wherein X is as previously defined).
