    Abstract: The present disclosure relates to a new method for producing alkali salt of bis(fluorosulfonyl)imide of high purity, as industrial scale, and with a reasonable cost when compared to the other available methods. Said method comprises the steps of reacting a bis(chlorosulfonyl)imide or a salt thereof with an onium chloride to produce an onium salt of bis(chlorosulfonyl)imide; reacting an onium salt of bis(chlorosulfonyl)imide with anhydrous hydrogen fluoride in at least one organic solvent to produce onium salt of bis(fluorosulfonyl)imide; and reacting the onium salt of bis(fluorosulfonyl)imide with an alkali salt to obtain alkali salt of bis(fluorosulfonyl)imide.

    Abstract: The invention provides a method of reversibly producing a source of hydrogen gas comprising mixing together a plurality of hydrogen-­containing starting materials; and then heating the mixed materials at a temperature sufficient to release hydrogen. Upon release of hydrogen, there is formed a residue which comprises at least one material different from the starting materials. There is also synergy whereby it is possible to regenerate at least one of the hydrogen-containing starting materials by exposing hydrogen gas to the aforesaid residue.

    Abstract: The invention concerns a fluorination method for obtaining fluorinated compounds. The method consists in reacting with an ionic fluoride of a monovalent cation a compound of formula (I), wherein: M represents H, an alkaline metal, a quaternary phosphonium group or a quaternary ammonium group; Y represents SO2, and m is 1, or Y is PO and m is 2; Z represents CR , N or P; R represents a carbonaceous and/or electron-attracting group which has a Hammet parameter sigma P higher than 0.4; R represents a carbonaceous and/or electron-attracting group; X represents a halogen other than a fluorine. The fluorinated compounds obtained are useful in particular as electrolyte in lithium batteries.
