Low-pressure solubilities of methane, ethane, propane, n-butane, iso-butane, and hydrogen have been measured in n-hexadecane, n-eicosane, squalane, bicyclohexyl, octamethylcyclotetrasiloxane, diphenylmethane, and 1-methylnaphthalene over the temperature range 25° to 200°C. The accuracy of these measurements is better than 1%. The data for the hydrocarbon gases have been correlated with a generalized configurational entropy and a van Laar-type interaction parameter. The entropic component of that parameter is related to the free volume of the solvent as suggested by Flory's equation-of-state theory of fluid mixtures. The accuracy of the correlation is about ±15%.
