Oligomeric surfactant based on octadecylamine and propylene oxide was synthesized. The degrees of oligomerization of octadecylamine was calculated as 6.2 Structure and composition of the surfactant was confirmed by using IR and UV-spectroscopy. Surface tension values with respect to concentration were examined and respective curve was plotted. Also, main surf activity parameters like CMC, CMC, πCMC, C20, pC20, Γmax, Amin were calculated. Critical micelle concentrations (CMC) and surface tensions at CMC were calculated as 1.58*10-4 mol/l and 31.92 mN/m respectively. Petrocollecting property and petrocollecting coefficients of the surfactant were studied for distilled, tap and sea water.
