Abstract

The inorganic salt content of alkane sulphonates, alcohol sulphates and olefin sulphonates can be reduced by treating the detergent active with a mixture of water and isopropanol and/or isobutanol with the conversion of bisulphite ions into sulphite ions. The treatment is performed under reflux at a temperature between boiling and 20 DEG C below boiling. A proportion of the inorganic material precipitates and is separated from the liquor which contains the active.
