Abstract
Acids, ketones, aldehydes, and alcohols were tested in the laboratory as substrates for hydrosulphurization under mild conditions. Ketone and aldehyde model compounds (i.e., 2-nonanone, nonanal, cholestan-3-one and phytenal) formed significant amounts of organic sulphur compounds, in which the oxo group was substituted by a polysulphide moiety. These results are used
