摘要

这份手稿报告了密度和粘度的新实验测量四氢糠醇+ 1-烷醇（1-丙醇1-庚醇）混合物，在0.1 MPa和温度范围从293.15 K至323.15 K。PC-SAFT可以准确预测混合物密度随1-烷醇浓度的降低而增加。此外，Redlich-Kister相关性允许正确地模拟过量摩尔体积和粘度偏差的实验数据，其可调参数通过保证每种混合物在每种温度下的偏差低于4.5%的标准获得。

Predictive PC-SAFT Approach for Density and Experimental Study of Properties in Tetrahydrofurfuryl Alcohol + 1-Alkanol (1-Propanol to 1-Heptanol) Mixtures

This manuscript reports new experimental measurements of density and viscosity of tetrahydrofurfuryl alcohol + 1-alkanols (1-propanol to 1-heptanol) mixtures, at 0.1 MPa and over a temperature range from 293.15 K to 323.15 K. PC-SAFT was used to correctly predict the increase in density of the mixture with decreasing 1-alkanol. Furthermore, the Redlich–Kister correlation allowed to correctly model experimental data of excess molar volume and viscosity deviation, whose adjustable parameters were obtained by a criterion that guaranteed a deviation lower than 4.5 % for each mixture and at each temperature.

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.
