AB  - In order to obtain evidence on the relationship between kerogen structural types and the quantity and nature of their oxidation products, the products of a multistage (13 step) alkaline permanganate degradation of type-III kerogen from a sample of the Mannville shale, Canada, have been studied in detail. High yield of oxidation products was obtained, 81.89% based on original kerogen: 0.61% neutrals and bases, 4.82% of ether-soluble acids, and 76.46% of precipitated ether-insoluble acids. The ether-soluble acids and the soluble acids produced by further controlled permanganate degradation of precipitated acids were found to consist of different mono- and polycarboxylic, partly alkyl-substituted, aromatic acids as major oxidation products (over 90%). Saturated unbranched mono- and dicarboxylic acids were found in small concentrations. In this way a typical aromatic structure of type-III kerogen was confirmed. The structure of the examined kerogen is probably largely alkyl-substituted and cross-linked by relatively short chains or bridges.

AB  - The products of a 27-step alkaline permanganate degradation of a type II kerogen from a sample of Toarcian shale, Paris Basin, have been studied. The high yield of oxidation products consisted of 1.86% neutrals and bases, 24.48% ether-soluble acids, and 45.95% precipitated, ether-insoluble acids, based on weight of original kerogen. The ether-soluble acids and the soluble products of further permanganate degradation of precipitated acids were found to consist mostly of saturated unbranched C6-C22 α,ω-dicarboxylic and C9-C25 monocarboxylic acids. Significant amounts of aromatic monocarboxylic, dicarboxylic and tricarboxylic acids were also found. Alkane tri- and tetracarboxylic acids were obtained in small concentration.
