Densities and viscosities for the binary system of tetraethylene glycol (1) + water (2) at T = (298.15 to 323.15) K were measured as a function of composition under atmospheric pressure. The excess properties, including excess molar volumes (\(V_{{\text{M}}}^{{\text{E}}}\)), viscosity deviations (Δη), and the excess Gibbs free energy of activation for viscous flow (ΔG*^E) were calculated by using density and viscosity data, respectively. Excess properties indicated that there are hydrogen bonding interactions between tetraethylene glycol and water molecules, which are investigated in detail by FTIR and UV–Vis spectra.

四乙二醇（1）+水（2）的二元体系的密度，粘度和光谱性质T =（298.15至323.15）K

在大气压下，测量四甘醇（1）+水（2）在T =（298.15至323.15）K下的二元体系的密度和粘度与组成的关系。过量的特性，包括过量的摩尔体积（\（V _ {{\ text {M}}} ^ {{\ text {E}}} \\）），粘度偏差（Δη）和过量的活化吉布斯自由能分别通过使用密度和粘度数据来计算粘滞流动性（ΔG * ^E）。过剩的性质表明四甘醇与水分子之间存在氢键相互作用，这已通过FTIR和UV-Vis光谱进行了详细研究。
