Abstract
Aliphatic sulphonic acids can be prepared by reacting n-paraffins with SO.sub.2 and O.sub.2 under UV irradiation with high selectivity even at conversions of up to 12 mol % if an amount of water is added which is appropriate to ensure that after the reaction has commenced and the stationary state has been reached, the sulphoxidation proceeds in homogeneous phase.
