Abstract:
The density(ρ), refractive index(nD), and dynamic viscosity(η), for the three binary solutions containing 1-decyl-3-methylimidazolium bromide(\[C10mim\]Br) and fatty alcohol{ethylene glycol (EG), 1,2-propanediol (PG), and 1-propanol (NPA)} were investigated,respectively at temperatures of 288.15~308.15 K and under ambient pressure.Additionally, the excess molar volume(VEm),and deviation of the refractive index(ΔnD), were calculated and correlated using the Redlich-Kister polynomial equation. The variation of density,refractive index and viscosity with the composition was described by the polynomial equations. The influence of carbon-chain length and the hydroxyl number of the fatty alcohol, and the influence of the temperature on the physicochemical properties of the binary systems can be explained by the comparison of the experimental results.
