The refractive index (nD) and density (ρ) values of the poly(ethylene glycol) (PEG) 1500 + dipotassium tartrate + water ternary system and physical properties of PEG 1500 + water and dipotassium tartrate + water binary solutions have been measured at 298.15 K and atmospheric pressure. Moreover, the refractive index deviation (ΔnD), viscosity deviation (Δη), apparent specific volume (Vφ), excess molar volume (VE), and excess Gibbs energy of activation for viscous flow (ΔG‡E) were calculated from the experimental measurements to analyze the behavior of the binary solutions and the refractive index deviation (ΔnD) and excess molar volume (VE) of the ternary solution. These results were fitted to Redlich–Kister polynomial and Cibulka Equations to estimate the interaction parameters. Adjustments were made to the refractive index and density to obtain a third-order polynomial expansion model and a second-order equation, respectively. The intermolecular interactions between the mixing components were demonstrated by the obtained data from the calculated functions.

298.15 K和大气压下的聚乙二醇，水和酒石酸二钾的二元和三元溶液的密度，粘度，折射率和过量性质
聚（乙二醇）（PEG）1500 +酒石酸二钾+水三元体系的折射率（n D）和密度（ρ）值和PEG 1500 +水和酒石酸二钾+水二元溶液的物理性能分别在1。 298.15 K和大气压。而且，折射率差（的Δn d），粘度偏差（Δη），表观比容（V φ），过量摩尔体积（V ë），并激活用于粘性流的过量Gibbs能（Δ ģ ‡ë）进行了计算从实验测量分析二进制方案的行为和折射率差（的Δn d）和三元溶液的过量摩尔体积（V E）。这些结果适合Redlich-Kister多项式和Cibulka方程，以估计相互作用参数。分别对折射率和密度进行调整，以获得三阶多项式展开模型和二阶方程。混合组分之间的分子间相互作用通过计算函数获得的数据得到证明。
