Abstract

In the present study, two sets of stimulants for the gemini surfactants derived from imidazole and indole were prepared, which contain a terminal chain containing eight carbon atoms and a separation between the two heads and two tails of the surface activating substance called 1, 5 – di bromo pentane. The prepared compounds were characterized using the FTIR and 1HNMR. The value of the critical micellization concentration (CMC) was calculated using electrical conductivity, as well as the value of the balance system between hydrophilic and lipophilic groups (HLB) to find out the appropriate application for them. The effectiveness of dispersion of oil spots in (oil/water) emulsions and biological activity on specific types of bacteria have also been studied.
