Oxidation of petroleum sulphides with nitrogen dioxide
Abstract 1. Petroleum sulphides (obtained as concentrates from appropriate distillates) were oxidized with a mixture of air and nitrogen dioxide to sulphoxides, with yields of 75 to 80% for sulphoxide sulphur, but the process was complicated by secondary processes: the formation of up to 30% of nitrosulphoxides of variable structure; sulphones and carbonyl compounds were present as traces. The target product was separated from most impurities by an alkaline wash, followed by chromatography. 2. Oxidation of individual sulphides under the conditions adopted gave sulphoxides, which contained only traces of compounds with a nitro-group, easily removed by recrystallization or elution chromatography.
