The hydrocarbon-type content of petroleum fractions has traditionally been determined by using different techniques but often with poor agreement among the various results for a given sample. In this study, three different fractions were analyzed by

The mass spectra of the monohydroxyquinolines, the monomethoxyquinolines, N-methyl-2-quinolone, and N-methyl-4-quinolone have been recorded. The isomeric hydroxy compounds vary somewhat in the stability of the molecular ion, but all show the same fra

At 95–115°, paraformaldehyde and hydriodic acid completely C-methylate aromatics such as benzene and phenol. Pyrroles are C-methylated similarly, carbethoxy and acetyl groups being lost. In hydriodic acid at 15–45°, typical pyrroles retain thes

Lobinaline, its derivatives, and its Hofmann degradation products have been examined by mass spectrometry and other spectral and chemical techniques. The results provide independent evidence for the structure of the alkaloid, but indicate that the fr

Sulfur compounds in the gas oil fractions from two bitumens (Athabasca oil sand and Cold Lake deposit), a heavy oil (Lloydminster) from Cretaceous reservoirs along the western Canada sedimentary basin, and a Cretaceous oil from a deep reservoir that
