Sažetak
Deep eutectic solvents (DESs) are considered as ˝green˝ replacement for hazardous industrial volatile organic solvents owing to their great physical and chemical properties. Low melting point, negligible vapor pressure, non-flammability, reuse, easy and cheap synthesis from non-toxic and biodegradable compounds make DESs attractive enough to take place in different fields of application. In this work the potential of DES [choline-chloride – glycerol, 1:1.5] for denitrification of a model fuel by means of liquid-liquid extraction is investigated. The model fuel solution consisted of n-heptane, n-hexane, i-octane, toluene and pyridine. The tie lines of the liquid-liquid equilibria for the ternary systems DES – n-heptane/n-hexane/i-octane/toluene – pyridine were experimentally determined at 25 °C and atmospheric pressure. The equilibrium data in ternary systems were described with NRTL and UNIQUAC models. The complete characterization of investigated DES with respect to refractive index, pH value, thermal conductivity, thermal diffusivity, thermal capacity, electrical conductivity, density and viscosity was performed as well at 25 °C and atmospheric pressure. The extraction efficiency shows similar values in the systems involving n-hexane, n-heptane and i-octane (~ 60 %) which is higher than the value found in the system comprising toluene (~ 43 %). Based on the obtained results it can be concluded that investigated DES can be considered as a potential solvent for fuel denitrification.
