Abstract Densities of pure ester diethyl tartrate and alcohols isobutanol and isopentanol are measured on high pressures up to 60 MPa and temperatures from 293.15 K to 413.15 K, while thermophysical properties for two systems ester + alcohol are obtained on atmospheric pressure and temperatures 288.15–323.15 K. High pressure densities were correlated with Tammann-Tait equation. Experimental data on atmospheric pressure for mixtures were used to determine derived properties, excess molar volume, viscosity and refractive index deviations, which are then correlated with Redlich-Kister polynomial equation. To support the discussion regarding interactions, FT-IR analyses of pure components and mixtures with highest absolute values of excess molar volume were presented. Additionally, viscosity modelling was performed with predictive and correlative models and results were discussed from the point of potential usage of applied models to calculate viscosity of investigated systems.

酒石酸二乙酯及其与异醇二元体系的热力学研究

摘要 在高达 60 MPa 的高压和 293.15 K 至 413.15 K 的温度下测量纯酯酒石酸二乙酯和醇异丁醇和异戊醇的密度，而在常压和温度 288.15–323.15 K 下获得酯 + 醇两种体系的热物理性质. 高压密度与Tammann-Tait 方程相关。混合物的大气压实验数据用于确定派生性质、过量摩尔体积、粘度和折射率偏差，然后与 Redlich-Kister 多项式方程相关联。为了支持关于相互作用的讨论，提出了对具有最高过量摩尔体积绝对值的纯组分和混合物的 FT-IR 分析。此外，
