POTENTIOMETRIC TITRATION OF ALKYLAMINE IN MICELLE

The potentiometric titration of long-chain alkylamine of micellar solubilization in aqueous phase has been studied. In the presence of 0.15mol/L of sodium dodecyl sulfate (SDS), laurylsulfonic acid sodium salt (LAS), dodecylbenzenesulfonic acid sodium salt (DBS), the weakly organic bases of dimethyldodecylamine, dimethyloctadecylamine, diethanoidodecylamine and diethanoloctadecylamine can be directly titrated with 0.1 mol/L hydrogen chloride and good shapes of titration curves are obtained. The results are the same as those of nonaqueous titration for the determination of samples in 0.15 mol/L SDS.
