The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

Laboratory heating experiments have been carried out using a mixture of isomeric C27 monoaromatic steroid hydrocarbons and 6(R), 10(S) pristane as organic substrate, each on a different sediment matrix. Under free radical conditions in the presence of elemental sulphur triaromatic steroid hydrocarbons and the 6(R), 10(R) and 6(S), 10(S) isomers of pristane were formed, respectively. Both the aromatisation and isomerisation reactions follow pseudo-first-order kinetics and rate constants have been measured. A qualitative investigation of the isomerisation of 5α(H)-cholestane shows that a complex mixture of C27 isomeric steranes is formed.
