摘要:
The present invention provides an industrially advantageous method for producing bis(halosulfonyl)amine that makes it possible to inhibit the rapid generation of gas and reduce the amount of halogenating agent used by controlling the reaction rate among sulfamic acid, the halogenating agent and a halosulfonic acid to nearly a constant rate from the initial stage to the final stage of the reaction. The method for producing bis(halosulfonyl)amine of the present invention allows the obtaining of a bis(halosulfonyl)amine such as N-(fluorosulfonyl)-N-(chlorosulfonyl)amine or bis(chlorosulfonyl)amine by a production method that includes heating a mixture containing sulfamic acid and a halosulfonic acid to a temperature higher than room temperature, adding a halogenating agent thereto, and allowing to react while adjusting to a prescribed temperature.

The invention relates to a method for preparing bis(fluorosulfonyl)imide acid, comprising: the reaction of sulphamic acid or one of the salts thereof with a halogenosulfuric acid and at least one fluorinating agent selected from SOF2, F—SO2—F and SF4, and the subsequent recovery of bis(fluorosulfonyl)imide acid. The invention also relates to a method for producing salts of bis(fluorosulfonyl)imide from the bis(fluorosulfonyl)imide acid thus produced.
摘要:
The present invention provides a method for producing a disulfonylamine alkali metal salt, including a step of subjecting a disulfonylamine onium salt represented by formula [I] (wherein each of R1 and R2 independently represents a fluorine atom or a fluorinated alkyl group having 1 to 6 carbon atoms, provided that at least one of R1 and R2 represents a fluorine atom, and each of R3, R4, R5 and R6 independently represents a hydrogen atom or the like) to a cation exchange reaction in an organic solvent, thereby producing a disulfonylamine alkali metal salt represented by formula [II] (wherein M+ represents an alkali metal cation, and R1 and R2 are as defined in formula [I]), and a step of filtering the organic solvent solution containing the disulfonylamine alkali metal salt through a filter having a particle retention size of 0.1 to 10 μm to obtain a filtrate.

摘要:
A mixture of sulphamic acid, a halogenated sulphonic acid and thionyl chloride is heated to allow the reaction to proceed, to thereby produce first intermediate products. The first intermediate products are then subjected to reaction with an alkali metal fluoride MF to produce second intermediate products. The second intermediate products is then subjected to reaction with the alkali metal fluoride MF in a polar solvent to obtain a desired product MN(SO2F)2 (where M is an alkali metal).
摘要:
The present invention is directed to methods comprising adding ammonia, either as an ammonium salt or as a gas at pressures below 0.01 MPa, to a sulfuryl fluoride solution to form the anion of bis(fluorosulfonyl)amine under conditions well suited for large-scale production. The bis(fluorosulfonyl)amine so produced can be isolated by methods described in the prior art, or isolated as an organic ion pair, such as an alkylammonium solid salt, or as an ionic liquid.

摘要:
Compounds containing sulphur-nitrogen groups, such as S.sub.4 N.sub.4, S.sub.5 N.sub.5.sup.+ salts and poly(sulphur nitride), are made by reducing S.sub.4 N.sub.3 Cl or related compounds with anions (e.g. iodide) or metals (e.g. silver). Poly(sulphur nitride) may be made by passing S.sub.4 N.sub.3 Cl vapor or S.sub.5 N.sub.5 FeCl.sub.4 vapor through sulphidized silver wool and condensing the vapor.
