Abstract
The composition of sulphur and nitrogen compounds contained in the bitumenoid isolated from Cambrian rocks oil shale formation was studied. It has been demonstrated that the sulphur compounds contain benzo-, dibenzo-, naphthobenzothiophenes and dibenzothiophene sulphoxides. Nitrogen compounds are presented by weak bases and neutral components. Among the weak bases, there are predominately alkyl homologues of dibenzoquinolone, dibenzothiaquinolone, dibenzoquinolinecarboxylic acids. The maximum in the distribution of neutral nitrogen-containing components corresponds to the alkyl derivatives of benzocarbazole and benzothiophenecarbazole as well as mononaphtheno derivatives of carbazolecarboxylic acids.
