摘要

本研究提供了含有癸酸甲酯和 1-烷醇（1-丙醇至 1-己醇）的混合物在 0.1 兆帕和不同温度（293.15 K 至 323.15 K）下的密度和粘度的新实验数据。我们分析了各组分之间的分子相互作用，发现它们之间的相互作用很微弱。PC-SAFT 状态方程在没有拟合参数的情况下准确地模拟了混合物的密度。该状态方程考虑了癸酸甲酯和 1-乙醇之间的氢键作用。此外，还成功地应用了两种粘度相关关系来拟合实验粘度数据，且准确度很高。

Experimental Measurements and Modeling of Density and Viscosity for Methyl Caprate + 1-Alkanol at Atmospheric Pressure and Different Temperatures

This study provides new experimental data for the density and viscosity of mixtures containing methyl caprate and 1-alkanol (1-propanol to 1-hexanol) at 0.1 MPa and different temperatures (293.15 K to 323.15 K). We analyzed the molecular interactions between the components and found that are weak. The PC-SAFT equation of state accurately modeled the density of the mixtures without fitted parameters. This equation of state considered hydrogen bonding between methyl caprate and 1-alkanol. Moreover, two correlations for viscosity were successfully applied to fit the experimental viscosity data with good accuracy.

期刊介绍： International Journal of Thermophysics serves as an international medium for the publication of papers in thermophysics, assisting both generators and users of thermophysical properties data. This distinguished journal publishes both experimental and theoretical papers on thermophysical properties of matter in the liquid, gaseous, and solid states (including soft matter, biofluids, and nano- and bio-materials), on instrumentation and techniques leading to their measurement, and on computer studies of model and related systems. Studies in all ranges of temperature, pressure, wavelength, and other relevant variables are included.
