METHOD FOR PRODUCING AMINO-SUBSTITUTED PHOSPHAZENE COMPOUND, METHOD FOR PRODUCING ELECTROLYTE SOLUTION FOR NONAQUEOUS SECONDARY BATTERIES, AND METHOD FOR MANUFACTURING NONAQUEOUS SECONDARY BATTERY

摘要

A method for producing an amino-substituted phosphazene compound, which comprises a step for substituting at least one fluorine atom of a fluorinated phosphazene compound by an amine compound by reacting the fluorinated phosphazene compound and the amine compound with each other in a reaction solvent, a step wherein the reaction solution after the reaction is mixed with an aqueous solution, thereby being separated into a phase of an amino-substituted phosphazene compound and a phase of a mixed solution of the aqueous solution and the reaction solvent, and a step for isolating the separated amino-substituted phosphazene compound; a method for producing an electrolyte solution for nonaqueous secondary batteries; and a method for manufacturing a nonaqueous secondary battery.
