| Popis: | The fuel microemulsions of water in a 4:1 (v:v) blend of gasoil and sunflower oil (respectively) by using of 1-dodecyl-3-methylimidazolium nitrate ([C12mim][NO3]) and 1-butyl-3-methyl imidazolium nitrate ([Bmim][NO3]) ionic liquids as surfactant and 1-butanol as co-surfactant. Also, the performance of 50:50 wt% blend of the mentioned ionic liquids with Span 80 as surfactant was evaluated in this work. The comparison of the phase diagrams of the samples has revealed a larger single phase region for samples prepared with ionic liquids than the conventional Span 80 surfactant or their blends with Span 80. The dynamic viscosity, and density of two samples with high oily phase content was measured according to the standards showing very close values to the net diesel fuel. DLS analysis indicated a water droplets of 9 nm (up to 70%) for [Bmim][NO3], 3–6 nm (up to 64–82%) for [C12mim][NO3], and 331 nm (up to 53%) for systems prepared by Span 80. Meanwhile, a very narrow size distribution was observed for the samples prepared by ionic liquids. No phase separation has been observed for the prepared samples over 6 months on the shelf. |
