摘要:
Granules or powders consisting of a compound of formula [I], in which a modal diameter is 80 μm or less, a median diameter is 45 μm 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.

摘要:
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.
摘要:
Disclosed is a method for producing “a salt or a complex comprising imide and an organic base”, characterized by reacting halogenated sulfuryl or halogenated phosphoryl with ammonia in the presence of an organic base. According to this method, a target imide compound can be produced in a high yield while significantly suppressing the production of by-products. Further, by reacting the obtained imide compound with an alkali metal hydroxide or an alkaline earth metal hydroxide, an imide metal salt can be easily derived.

摘要:
Solutions of nitrosylsulfuric acid in sulfuric acid are manufactured by reacting nitric acid with sulfur in sulfuric acid or oleum. Less than 0.33 gram atom of sulfur is employed per mole of nitric acid, and after completion of the reaction the free nitric acid still present in the nitrosylsulfuric acid solution is reduced with lactones.
