  • Granules or powder of disulfonylamide salt and method for producing same
    Patent number: 10214419
    Abstract: Granules or powders consisting of a compound of formula [I], in which a modal diameter is 80 ?m or less, a median diameter is 45 ?m or less, and/or, a ratio of (modal diameter)/(median diameter) is 1.7 or less, are preferably used for an electrolyte or the like. In formula [I], R1 and R2 each independently represents a fluoroalkyl group having 1 to 6 carbon atoms, or a fluorine atom, and Y+ represents an alkali metal cation or an ammonium cation.

  • Process for producing fluorine-containing sulfonylimide salt
    Patent number: 9233849
    Abstract: 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.

  • Production process for fluorosulfonylimide ammonium salt
    Patent number: 9096502
    Abstract: A compound [II] such as ammonium N,N-di(fluorosulfonyl)imide is obtained by reacting a compound [I] such as N,N-di(chlorosulfonyl)imide and NH4F (HF)p. A compound [IV] such as an N,N-di(fluorosulfonyl)imide alkali metal salt is obtained by reacting the obtained compound [II] and an alkali metal compound or the like.
