Porphyrins of high molecular weight in a triassic oil shale: evidence by gel permeation chromatography
Technical Report
·
OSTI ID:6960246
The porphyrin pigments in extracts of the Triassic oil shale of Serpiano (Switzerland) were separated by gel permeation chromatography over alkylated Sephadex (LH-20) and Styragel. Evidence is presented for the existence of homologous series of pigments extending into the high molecular weight region (above 20,000 mol. wt.). These pigments are believed to be the products of heterogeneous polymerization of porphyrins derived from biological sources with the bulk organic matter of the sediment. The geochemical significance of this finding is discussed.
