Description
Summary:The synthesis of surfactants derivatives of new two series of cationic gemini surfactants containing ethane or benzene as a spacer are described. The prepared compounds were analyzed using standard tools of analysis, elemental analysis, FTIR measurements, and H 1 NMR spectra. The influence of dimerization and of the spacer group were examined in order to establish structure-property relationships. The critical micelle concentration (CMC) of each series has been determined using equilibrium surface tension measurements. Furthermore, air/water interface parameter including effectiveness (Π cmc ), efficiency (P20), maximum surface excess (τ max ), and minimum surface area (A min ) have been also derived using Gibbs adsorption equation at 25°C. Standard free energies of micelleization were calculated and biological activities were examined. The results revealed that the dimeric surfactants have a good effect on the biological activities.
