Abstract
1. A process for the preparation of perhalomethanesulphinic acid salts of general formula (I) [X1 X2 FC - SO2 ]3-n M in which X1 and X2 represent an identical or different halogen atom chosen from F, Cl and Br, M represents an alkali metal or alkaline-earth metal, n is equal to 1 or 2 depending on the valency state of the metal M, characterized in that an alkali metal or alkaline-earth metal dithionite of general formula Mn (S2 O4 ) (II) in which n and M have the above meaning, or a hydroxymethanesulphinate is brought into contact with a perhalomethane in a polar solvent.
