Two successive degradation steps involving Na 2 Cr 2 O 7 /AcOH and RuO 4 were carried out on a Type II-S kerogen from the Miocene Monterey Formation (California) after pre-saponification of the ester bonds by KOH/MeOH treatment. Detailed gas chromatography (GC) and gas chromatography–mass spectrometry (GC–MS) analysis of the soluble acids revealed significant qualitative...
Ruthenium tetroxide oxidation was applied to sulfur-rich kerogens from the Nördlinger Ries, southern Germany, to provide complementary structural information about the nature of alkyl substituents attached to aromatic moieties. The oxidation products contained series of straight-chain monocarboxylic acids (C 8 –C 29 ), α,ω-dicarboxylic acids (C 7 –C 26 ), isoprenoid...
