Abstract Solubilities for 13 gases and vapours (CO 2 , alkanes from ethane to n‐octane, benzene, toluene, xylene, dichloromethane, and methanol) in two Alberta bitumens (Athabasca and Wolf Lake) have been measured at several temperatures (30‐150°C), using gas‐liquid chromatography (GLC). The GLC method yields accurate solubilities and Henry's law constants for moderately soluble gases, but is not applicable to less soluble gases such as CH 4 and H 2 . Results have been used for calculations of Δ H o and Δ C o p for processes of the type Solute Substance (gas) = Solute Substance (in bitumen). Correlations of Henry's law constants and Δ H o values with carbon number for alkanes have been observed and used for predictions of CH 4 solubilities in bitumens.
