โฆ Synopsis
Definite, but overall slight molecular degradation occurs when Athabasca asphaltenes react with common oxidizing agents. Application of proton magnetic resonance spectroscopic analysis to the products illustrates the overall effects of the oxidation processes on the aromatic sheets of the asphaltenes and, in conjunction with other analytical techniques, indicates plausible routes by which degradation may occur.

interaction of Athabasca asphaltene with a hydrogendonating solvent such as tetralin at temperatures between 195 and 39O'C has been investigated. The reaction resulted in lowering the molecular weight of the treated asphaltene. At 390ยฐC, 50% of the original asphaltene was converted into pentane-solu
Athabasca bitumen separated from the associated mineral matter by Soxhlet extraction contains fine clay particles and inherent ash. Empirical relations have been developed to estimate the percentage of clay and inherent ash present in the asphaltene fraction which concentrates in large measure the m
Colloidal dispersions of Athabasca asphaltenes in toluene were studied at room temperature by small-angle X-ray scattering (SAXS). Both 5% and 15% dispersions were found to be polydispersed spheres with the main distribution peak at a concentration-independent average radius of 33 A. The main distri
The interactions of Athabasca asphaltenes and heavy oil with metal chlorides are described. The asphaltenes are converted to insoluble, presumably higher molecular weight, products which contain substantial amounts of chemically bound chlorine. The heavy oils were converted partly into insoluble pro
