Lithiumfluorosulfonat , LiSO 3 F is the lithium - salt of fluorosulfonic .

Extraction and presentation

The compound can be generated by the reaction of lithium chloride and fluorosulfonic acid at 120 ° C.

The reaction of lithium hydroxide and fluorofluorosulfonate can also produce the salt.

One method of extraction would be the reaction of lithium hydroxide and ammonium fluorosulfonate .
