Heating of C20 (Ia) and C28 (Ie, 20R) triaromatic steroid hydrocarbons on bentonite at 200°C results in their presumed degradation to unknown products, although traces of Δ15 and 20S (for the C28 compound) components were observed. No short chain, C20 (Ia) and C21 (Ib) triaromatics were obtained from the C28 triaromatic. Competitive heating of equal amounts of C20 and C28 components showed a faster rate of degradation for the long chain homologue. This suggests that the increase in short chain triaromatics in sediments upon increasing maturation may be due to preferential degradation of the long chain homologues.
