✦ Synopsis

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 390°C, 50% of the original asphaltene was converted into pentane-solubles and the sulphur and oxygen contents were each depleted by about 40%. The results, which were interpreted in terms of thermal cleavage of sulphide bonds, are complementary to those obtained in the radical-ion electron-transfer reduction of the asphaltene with potassium in tetrahydrofuran. The negligible amount of coke formation at 390°C proves the excellent stabilizing properties of tetralin in thermal reactions.

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

The asphaltene of the Athabasca bitumen exhibits a single, structureless e.s.r. signal at a g-value of 2.0032 with an intensity corresponding to approximately one free spin per ninety molecules. From the temperature dependence of the absorption it is concluded that absorption is due to stable polycy
