Abstract

This work presents experimental data on the density and viscosity of mixtures composed of nonanal and 1-alkanols (ranging from 1-propanol to 1-heptanol) at 0.1 MPa and within the temperature range of 293.15 K to 323.15 K. The resulting properties, including excess molar volume and viscosity deviation, were fitted using the Redlich–Kister equation. Moreover, the PC-SAFT equation of state successfully reproduced the experimental density results. The study also revealed that the intermolecular interactions between nonanal and the 1-alkanols can vary in strength (strong or weak).

壬醛+ 1-烷醇（C3-C7）二元混合物的热物理和体积性质：温度为（293.15 ~ 323.15）K的实验和模拟研究

本文介绍了由壬烷醇和1-烷醇组成的混合物（从1-丙醇到1-庚醇）在0.1 MPa和293.15 K至323.15 K温度范围内的密度和粘度的实验数据。所得的性质，包括过量摩尔体积和粘度偏差，用Redlich-Kister方程拟合。此外，PC-SAFT状态方程成功地再现了实验密度结果。该研究还揭示了壬醛和1-烷醇之间的分子间相互作用可以在强度（强或弱）上有所不同。

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.
