在288.15 K至323.15 K温度区间和大气压下测定了不同分子量的2-丁醇和聚乙二醇、四乙二醇二甲醚或N-甲基-2-吡咯烷酮的二元混合物的密度、粘度和折射率的实验数据。根据这些数据计算过量摩尔体积、粘度偏差和折射率偏差，并与 Redlich-Kister 多项式方程相关。获得的结果可以解释特定的分子间和分子内相互作用。
Experimental data on densities, viscosities, and refractive indices of binary mixtures with 2-butanol and polyethylene glycols of different molecular weights, tetraethylene glycol dimethyl ether, or N-methyl-2-pyrrolidone, were determined in the temperature interval from 288.15 K to 323.15 K and at atmospheric pressure. Excess molar volumes, viscosity deviations, and deviations in refractive indices were computed from these data and correlated with the Redlich–Kister polynomial equation. The obtained results allowed the interpretation of specific inter- and intramolecular interactions.
