采用实验和分子模拟的方法研究了水+甲醇+乙醇混合液的互扩散。在环境条件下,所有三个二元子系统的Fick扩散系数测量作为一个功能的组合物的泰勒色散。对于含水系统,这些数据与文献值比较好。在甲醇+乙醇的情况下,菲克扩散系数的实验测量首次提出。通过分子模拟,以一致的方式预测了三元混合物及其二元子系统的Maxwell-Stefan扩散系数和热力学因子。所得的菲克扩散系数进行比较,目前的测量和从经典的模拟方法,这需要实验汽液平衡或过量焓数据。此外,自扩散系数和剪切粘度的分子动力学预测和有利的实验文献值相比。所提出的三元扩散数据应有利于极性和氢键系统的扩散系数的聚合预测模型的发展。
Mutual diffusion is investigated by means of experiment and molecular simulation for liquid mixtures containing water + methanol + ethanol. The Fick diffusion coefficient is measured by Taylor dispersion as a function of composition for all three binary subsystems under ambient conditions. For the aqueous systems, these data compare well with literature values. In the case of methanol + ethanol, experimental measurements of the Fick diffusion coefficient are presented for the first time. The Maxwell-Stefan diffusion coefficient and the thermodynamic factor are predicted for the ternary mixture as well as its binary subsystems by molecular simulation in a consistent manner. The resulting Fick diffusion coefficient is compared to present measurements and that obtained from the classical simulation approach, which requires experimental vapor-liquid equilibrium or excess enthalpy data. Moreover, the self-diffusion coefficients and the shear viscosity are predicted by molecular dynamics and are favorably compared to experimental literature values. The presented ternary diffusion data should facilitate the development of aggregated predictive models for diffusion coefficients of polar and hydrogen-bonding systems.
