<p>By reacting a fluorine-containing sulfonylimide ammonium salt such as ammonium N,N-di(fluorosulfonyl)imide with an alkali metal hydroxide such as lithium hydroxide, potassium hydroxide or sodium hydroxide under reduced pressure and at a low temperature of approximately 40°C, a fluorine-containing sulfonylimide alkali metal salt such as lithium N,N-di(fluorosulfonyl)imide, potassium N,N-di(fluorosulfonyl)imide or sodium N,N-di(fluorosulfonyl)imide is obtained.</p> |
