Abstract

Sulphonic acid soln. is degassed soln. and one or more weakly polar alcohols contg. at least 5C atoms, in the molecule, are added to separate the mixture into an org. phase contg. all of the sulphonic acids, and an aqs. phase contg. almost all of the H2SO4. The aqs. phase is separated and the organic phase is treated to separate the sulphonic acids in the form of the free acids on their acetal, salts. This procedure is esp. suitable for treating crude sulphonic solns. produced by the sulphoxidation of n-paraffins contg. 7-30 pref. 10-20C atoms.
