Three anionic surfactants (Na-octysulfoacetate (A8), Na-dodecylsulfoacetate (A12), and Na-cetylsulfoacetate (A16) were prepared from alkyl bromoacetate. Several studies were carried out with aqueous surfactant solutions including surface tension, and electrical conductivity measurements. Surface properties, in particular, critical micelle concentration (CMC), effectiveness (ΠCMC), efficiency (Pc20), maximum surface excess (Γmax), and minimum surface area (Amin) were investigated at different concentrations at 20, 35 and 50°C, respectively. Free energies, enthalpies, entropies of micellization, and adsorption of the surfactants in the aqueous solution were studied.
