Solubility of non-polar gases in cyclohexanone between 273.15 and 303.15 K at 101.32 kPa partial pressure of gas

Abstract

Solubility measurements of several non-polar gases (He, Ne, Ar, Kr, Xe, H2, D2, N2, O2, C2H4, C2H6, CF4, SF6, andCO2) in cyclohexanone at 273.15 to 303.15 K and a partial pressure of gas of 101.32 kPa, are reported. Gibbs energy, enthalpy, and entropy of solution at 298.15 K and 101.32 kPa partial pressure of gas were evaluated. Effective hard-sphere diameter temperature dependence has been studied and its effect on the calculated SPT (Scaled Particle Theory) solubilities, and enthalpies and entropies of solution was also examined.

Fluid‐phase coexistence for the oxidation of CO2 expanded cyclohexane: Experiment, molecular simulation, and COSMO‐SAC

“…For these three binary systems, all models were adjusted to the Henry's law constant, compared in Table . Molecular simulation and COSMO‐SAC (both in adjusted mode) show a similar agreement with the experimental data for H CO 2 , j of these systems, compared in Figure . The agreement is excellent at lower temperatures, but at higher temperatures they overpredict.…”

“…Due to the large difference in terms of the volatility between oxygen and the cyclic compounds, exclusively data on the Henry's law constant are available in the literature for oxygen + cyclohexane, oxygen + cyclohexanone, and oxygen + cyclohexanol, compared in Figure . With an adjusted binary parameter ( ξ = 0.91, 0.93, and 0.90), the molecular simulation results are in excellent agreement with the experiment for all three systems throughout the entire temperature range for which experimental data are available. COSMO‐SAC underpredicts the Henry's law constant with a maximum deviation of around 55% at low temperatures.…”

Solubility of nonpolar gases in 2,6-dimethylcyclohexanone

“…from the solubility data of rare gases at different temperatures (23), and l1 = -1.48 X lop4 K-' from enthalpy solution data (24). The agreement between both methods is ordinary (4,7,24). Once the parameters for the solvent were known, calculations were made to obtain the theoretical values of the thermodynamic functions in the solution process.…”

“…This paper is a continuation of our work on the solubility of non-polar gases (1)(2)(3)(4)(5)(6)(7)(8) to study the influence exerted by the presence of different features in the solvent molecule. In this particular case we were interested in seeing how the solubility changes with the introduction of methyl groups as substituents in the solvent cyclohexanone.…”

“…In this particular case we were interested in seeing how the solubility changes with the introduction of methyl groups as substituents in the solvent cyclohexanone. Previously, the solubility of fourteen non-polar gases in cyclohexanone and 2-methylcyclohexanone was measured and published in this journal (4,7).…”
