| Summary: | In this paper, trihexyltetradecylphosphonium
dioctylsulfosuccinate [P6,6,6,14][docusate] was synthesised by anion metathesis using sodium dioctylsulfosuccinate salt. The molecular structure of the synthesisied IL was confiremed by using 1H NMR and elemental analysis and also physical properties such as density, viscosity and refractive index were studied as a function of temperature at the atmospheric pressure. The experimental values of density and refractive index decreases linearly with increasing temperature. The density, refractive index and viscosity of the present IL at 298.15 K are 0.9631 g.cm-3, 1.47190 and 1806.1 mPa.s respectively. The results show that this IL possesses higher viscosity, similar density and refractive index compared to the other hexyltetradecylphosphonium ILs. |
