摘要
本文测定了温度288.15～333.15 K和常压下溴化1-己基/辛基-3-甲基咪唑离子液体([C_6mim]Br/[C_8mim]Br)+1,2-丙二醇/1-丙醇二元体系的密度(ρ)、折光率(nD)和黏度(η),计算获得了超额摩尔体积(V_m~E)和折光率偏差(Δn_D),并用Redlich-Kister方程对衍生性质数据进行拟合.密度、折光率和黏度值随组成的变化用多项式方程进行了拟合,讨论了醇、离子液体以及温度对二元体系物化性质的影响.
In the present work, the density, ρ, refractive index, nD, and dynamic viscosity, η, for four binary solutions containing ionic liquids [C_nmim]Br(C_nmim=1-alkyl-3-methylimidazolium, n=6, 8) and 1,2-propanediol(PG)/1-propanol(NPA), at temperatures 288.15–333.15 K and ambient pressure were investigated. Additionally, the excess molar volume, V_m~E, and the refractive index deviations, Δn_D, were calculated and correlated using the Redlich-Kister polynomial equation. The density, refractive index, and natural logarithm of dynamic viscosity of the binary mixtures were correlated using empirical equation. The influence of alcohol, ionic liquids, and temperature on the physicochemical properties was discussed.
