ABSTRACT:
The purpose of the process of the present invention is to remove excess sulfuric acid from a mixture of paraffin-sulfonic acids free or substantially free, from paraffins.
In order to remove said sulfuric acid, according to the process of the present invention, the paraffin-sulfonic acid mixture is mixed with one or more halogenated solvent(s), possibly in mixture with sulfuric acid to form a two phase mixture consisting of an organic phase containing paraffin-sulfonic acids dissolved therein and an aqueous phase substantially containing sulfuric acid. The organic phase is then treated with sulfuric acid and the organic phase and aqueous phase are then separated and the organic phase is submitted to evaporation, for the removal of the halogenated solvent(s), and with the concentrated paraffin-sulfonic acids being obtained.
