Abstract
The eutectic mixtures consist of dl-menthol and acetic acid were prepared at five molar ratios (3:1, 2:1, 1:1, 1:2, 1:3). The vibrating-tube densimeter was used to measure the density of the DL-menthol/acetic acid mixtures, and the measurements were carried out from 293.15 K to 363.15 K and pressures from 0.1 MPa to 70 MPa. The measured densities of each dl-menthol/acetic acid mixture at different temperature and pressure were correlated by the Tait equation. In addition, the derived properties of dl-menthol/acetic acid mixtures including isothermal compressibility, isobaric thermal expansivity, and internal pressure were calculated. The effects of temperature, pressure, and molar ratios on the derived properties were compared and analyzed.
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.
