Abstract

This manuscript investigates different properties of binary mixtures composed of methyl heptanoate and a series of 1-alkanols (from 1-propanol to 1-hexanol) at atmospheric pressure (0.1 MPa) and temperatures ranging from 293.15 K to 323.15 K. Our experimental data shows that weak intermolecular interactions between the methyl heptanoate and 1-alkanol. Additionally, we employed the PC-SAFT equation of state to accurately predict the density of the mixtures. On the other hand, two viscosity correlations (Redlich–Kister and Belda) were also tested, both of which provided a good fit to the experimental viscosity data.

酯-醇相互作用的理论建模和实验研究：庚酸甲酯和1-烷醇

本文研究了由庚酸甲酯和一系列1-烷醇（从1-丙醇到1-己醇）组成的二元混合物在大气压（0.1 MPa）和293.15 ~ 323.15 K温度范围内的不同性质。我们的实验数据表明，甲基庚酸酯和1-烷醇之间存在弱的分子间相互作用。此外，我们采用PC-SAFT状态方程来准确预测混合物的密度。另一方面，还测试了两种粘度相关性（Redlich-Kister和Belda），两者都与实验粘度数据吻合良好。

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.
