✦ Synopsis

Reactions of resins, asphaltenes and model nitrogen compounds with acetic anhydride and with trifluoroacetic anhydride yield compounds which provide indications that the predominant nitrogen functional groups in resins and asphaltenes (from Athabasca bitumen) exist as imino groups of the carbazole-type.

Evidence for this was obtained from infrared and F" nuclear magnetic resonance studies.

Infrared and chemical studies of the resin fraction isolated from Athabasca bitumen indicate that oxygen in these fractions exists predominantly as ester functions. Evidence for this was obtained from hydrolysis, acetylation and methylation reactions.

## Abstract Experimental data for the diffusivity of carbon dioxide, methane, ethane and nitrogen in Athabasca bitumen are presented in the range 25–90Β°C at 4 and 8 MPa. The diffusivity of these gases has been determined as a function of gas concentration in bitumen using a non‐intrusive experimΜ€en
