Study of the chemical nature of petroleum components of high molar mass from Russian fields
Abstract 1. Adsorption chromatography on wide-pore adsorbent-Silochrome-was used to segregate components of native petroleum asphaltenes into fractions with very different oxygen and sulphur contents, average molecular weights and aromaticity. 2. Russian petroleum resin molecules contain aromatic (tri- or tetracyclic on average) blocks containing one or more nitrogen atoms. Polar substances which form the main part of resins contain long, slightly branched aliphatic chains. Low-polarity compounds form a smaller proportion of resin components, their molecules probably contain large, polycyclane fragments which are not condensed with aromatic nuclei. 3. Asphaltene components, on the whole, are more aromatic than the resinous components and independent of the molar mass of the fractions, contain aromatic nuclei of similar average dimensions, differing mainly in the number of such nuclei in molecules.
