The article describes a new and effective synthesis of pure imido-bis(sulfuric acid) dihalogenides (halogenide = F, Cl) and the potassium salt of imido-bis(sulfuric acid) difluoride, KN(SO2F)2.

METHOD FOR PREPARING BIS(FLUOROSULFONYL)IMIDE

The invention relates to a method of preparing lithium bis(fluorosulfonyl)imide, comprising: reacting lithium bis(chlorosulfonyl)imide with an alkali metal fluoride used as a fluorinating agent in a solvent of saturated alkyl carbonate and/or saturated fluoroalkyl carbonate in the presence of a crownether phase transfer catalyst adaptive to the alkali metal fluoride to obtain lithium bis(fluorosulfonyl)imide. The method of preparing lithium bis(fluorosulfonyl)imide according to the invention possesses a simple process route, and industrial manufacture can be realized easily.
