“…Thus, measurements with an Anton Paar DMA 602 vibrating-tube densimeter of the density changes caused by dissolved air, nitrogen, oxygen, hydrogen, methane and carbon dioxide in n-alkanes (heptane, octane, nonane, decane, dodecane, tetradecane and hexadecane), cyclohexane, methylcyclohexane and toluene were undertaken 158 at 298.15 K and a total pressure of 101 kPa to determine V LN 2 . There is some overlap between this work and the data set of the research group of Cibulka and Heintz, 155,156 with reasonably good agreement. Ashcroft et al found that the partial molar volumes of all the gases decrease with increasing carbon number of the alkane series, and that at the same experimental conditions nitrogen and methane have almost the same partial molar volume in the n-alkanes.…”

“…The estimated maximum imprecision of the results is AE 1.5 cm 3 mol À1 , or about AE (1.5% to 4%), and they compare well with literature values determined conventionally. Vibrating-tube densimetry has also been used by Cibulka and coworkers 155,156 to determine V LN 2 of nitrogen, oxygen, argon, carbon dioxide and air dissolved in several liquid n-alkanes and alkan-1-ols at 298.15 K and 313.15 K and ambient pressure. During an earlier investigation of the shrinkage observed when crude oils are spiked with light alkanes, Ashcroft et al 157 noted the paucity of experimental data on the effect of dissolved gases on the densities of pure liquid hydrocarbons.…”

“…Therefore, the partial molar volumes of these gases must be considered for the data treatment in procedure (a). Fortunately, there are reliable methods for estimating the partial molar volumes (11)(12)(13)(14) from the critical data T c and p c of the gases and the internal pressure p in of the solvents defined by:…”

“…The exponential in Eq. 306 is known as Poynting correction factor; its evaluation requires reliable data on the partial molar volume of the solute at infinite dilution [224][225][226][227][228][229][230][231][232][233][234][235][236].…”

The liquid state is one of the three principal states of matter and arguably the most important one; and liquid mixtures represent a large research field of profound theoretical and practical interest. This topic is of importance in many areas of the applied sciences, such as in chemical engineering, geochemistry, the environmental sciences, biophysics and biomedical technology. First, I will concisely present a review of important concepts from classical thermodynamics of nonelectrolyte solutions; this will be followed by a survey of (semi-)empirical approaches to representing the composition and temperature dependence of selected thermodynamic mixture properties, and finally the focus will be on dilute binary nonelectrolyte solutions where one component, a supercritical solute, is present in much smaller quantity than the other component, called the solvent. Partial molar properties in the limit of infinite dilution (indicated by a superscript ∞) are of particular interest. For instance, activity coefficients (Lewis–Randall (LR) convention) are customarily used to characterize mixing behavior, and infinite-dilution values $$\gamma_{i}^{{{\text{LR,}}\infty }}$$ γ i LR, ∞ provide a convenient route for obtaining binary parameters for several popular solution models. When discussing solute (j)—solvent (i) interactions in solutions where the solute is supercritical, the Henry fugacity $$h_{j,i} \left( {T,P} \right)$$ h j , i T , P , also known as Henry’s law (HL) constant, is a measurable thermodynamic key quantity. Its temperature dependence yields information on the partial molar enthalpy change on solution $$\Delta H_{j}^{\infty } \left( {T,P} \right)$$ Δ H j ∞ T , P , while its pressure dependence yields information on the partial molar volume $$V_{j}^{{{\text{L,}}\infty }} \left( {T,P} \right)$$ V j L, ∞ T , P of solute j in the liquid phase (superscript L). I will clarify issues frequently overlooked, touch upon solubility data reduction and correlation, report a few recent high-precision experimental results on dilute aqueous solutions of supercritical nonelectrolytes, and show the equivalency of results for caloric quantities (e.g. $$\Delta H_{j}^{\infty }$$ Δ H j ∞ ) obtained via van ’t Hoff analysis of high-precision solubility data with directly measured calorimetric data.
