Abstract
The electrical conductivity/concentration data of aqueous solutions of n-hexadecyl-trimethylammonium bromide (CTAB), an cationic surfactant, with two ammonium based ionic liquids propyl-(2-hydroxyethyl)-dimethyl-ammonium bromide, (C3Br), butyl-(2-hydroxyethyl)-dimethyl-ammonium bromide, (C4Br) of high melting points (>373 K) were determined in the temperature range 298.15–328.15 K. These data were used to determining the critical micelle concentration (CMC) in function of concentration and temperature. The two ionic liquids and the surfactant have the same anion and the ammonium based cation. The influence of ionic liquids on the micellisation process of the CTAB is discussed.
