摘要：The invention relates to a process for the preparation of beta-substitutedsulphonic acids and/or sulphonates which comprises reacting a beta-sultone of aninternal olefin having the chemical formula wherein each of the groups R₁, R₂, R₃ and R₄independently are linear or branched alkyl groups or hydrogen and the total number ofcarbon atoms of R₁, R₂, R₃ and R₄ is from 6 to 24, and at least one of R₁ and R₂ and one ofR₃ and R₄ is an alkyl group, with a nucleophile, with the proviso that the nucleophile is notH₂O or hydroxide ion.
