Three asymmetric dicationic ionic liquids; 1-(2-(1-dodecyl-2-methyl-1H-imidazol-3-ium-3-yl)ethyl)-4-methylpyridin-1-ium bromide, 1-(6-(1-dodecyl-2-methyl-1H-imidazol-3-ium-3-yl)hexyl)-4-methylpyridin-1-ium bromide and 1-(10-(1-dodecyl-2-methyl-1H-imidazol-3-ium-3-yl) decyl)-4-methylpyridin-1-ium bromide (Ia, Ib &Ic respectively) were synthesized and characterized via Elemental analysis, FT-IR, 1H NMR, and Thermo-gravimetric analysis (TGA). Their surface activities were studied. The performance of the synthesized ionic liquids as oil spill dispersants were evaluated at different temperatures (10, 30 & 50 °C) and concentrations (750, 1500, 2000, 3000 ppm). Data reveals that the efficiency is ranked as follows: Ib > Ia > Ic with concentration of 1500 ppm.
