Abstract A process for separating and recovering paraffin sulphonic acids from mixtures with water and sulphuric acid is described, consisting of: bringing such a mixture into contact under extraction conditions with a saturated aliphatic or cycloaliphatic liquid hydrocarbon; separating an aqueous liquid phase containing sulphuric acid from an organic liquid phase consisting of the extraction solvent containing the paraffin sulphonic acids; and recovering the paraffin sulphonic acids from said organic liquid phase. The process is particularly applicable to products obtained from processes involving the sulphoxidation of paraffins with sulphur dioxide and oxygen, catalyzed by U.V. radiation.
