在大气压力0．1 MPa 及288．15～308．15 K 温度下测定了溴化1-癸基-3-甲基咪唑离子液体（[C10 mim]Br）＋脂肪醇｛乙二醇（EG）／1，2-丙二醇（PG）／正丙醇（NPA）｝三个二元体系的密度（ρ）、折光率（nD ）和黏度（η）。计算获得了过量摩尔体积（V Em ）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。通过对实验数据的比较，总结出脂肪醇的碳链长度和羟基个数以及温度等对物化性质的影响。

The density(ρ),refractive index(nD ),and dynamic viscosity(η),for the three binary solutions containing 1-decyl-3-methylimidazolium bromide([C10 mim]Br)and fatty alcohol{ethyl-ene 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(V Em ),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 physi-cochemical properties of the binary systems can be explained by the comparison of the experimen-tal results.
