There are inconsistencies in the literature regarding the role of organosulfur compounds in general, and sulfonic acids in particular, on the oxidative instability of middle distillate fuels. Comparison of published results between investigations is complicated by differences in a large number of variables. Variations in fuel composition, heteroatom distribution, reaction surface, hydroperoxide concentration, dissolved oxygen, and reaction temperature all contribute to the variation in observed results. In an effort to clarify this situation, with respect to sulfonic acid formation, the authors have examined the tert-butyl hydroperoxide liquid-phase oxidation reactions at 120C of hexyl sulfide and hexyl disulfide in deaerated benzene solvent. They report the product slate and and its distribution with reaction time and propose a mechanism that is consistent with the observed product slate.
