Procedure

Sodium bis(2-ethylhexyl)sulfosuccinate (NaAOT) is obtained from Fisher. 10 g NaAOT is dissolved in 100 mL diethylether and combined with an equal volume of 0.1 M aqueous AgNO3 in a separatory flask. The mixture is shaken and the aqueous phase was decanted. Two additional 100 mL volumes of 0.1 M AgNO3 are similarly ion exchanged with the ether solution. The ether solution is then washed twice with deionized water. The aqueous phase is decanted and the ether phase is reduced to a paste using rotary evaporation. The remaining paste is dried in a vacuum oven at 25-50° C., and a yield in excess of 90% is obtained.
