Abstract

A process for separating the alkylsulphonic acids with a linear alkyl chain from the crude sulphoxidation products of linear paraffins by treating these crude products with acyclic aliphatic ethers, then separating the two phases thus obtained and finally recovering the alkylsulphonic acids from the aqueous-organic phase.
