Zusammenfassung:1. Process for the production of alkane sultones of the general Formula (I) : see diagramm : EP0099021,P4,F1 wherein : R**1 denotes hydrogen or methyl, and m denotes 0 or 1, characterised by thermal decomposition of sulphoalkyl-aryl ethers of the general Formula (II) at a temperature between 80 and 250 degrees C : see diagramm : EP0099021,P4,F2 wherein : R**1 denotes hydrogen or methyl, m denotes 0 or 1, and R**2 , R**3 , R**4 , R**5 and R**6 denote hydrogen or identical or different substituents, namely methyl, ethyl, halogen or alkoxy, or R**3 together with R**2 or together with R**4 denotes a radical to complete a fused-on 5- or 6-membered ring.
