[en] The solubility of He, Ne, Ar, Kr, N₂, O₂, CO, CO₂, CH₄, CF₄, and SF₆ in cis-1,2-dimethylcyclohexane, trans-1,2-dimethylcyclohexane, and two binary mixtures of cis- + trans-1,3-dimethylcyclohexane and cis- + trans-1,4-dimethylcyclohexane, respectively, have been determined at 1 atm pressure in the range 297 to 313 K. From the experimental results, the enthalpy and entropy changes on solution for 1 atm partial pressure of gas and 298.15 K have been calculated. These values have been compared with results obtained through application of scaled-particle theory. Agreement is generally quite satisfactory. On this basis, a recent semi-empirical correlation advanced by Field, Wilhelm, and Battino is tested. (author)
