Fig. 1: Reaction scheme of the oxidation of reduced-sulfur emissions, i.e. CH3SH (MeSH, methylthiol), CH3SCH3 (DMS, dimethyl sulfide) and CH3SSCH3 (DMDS, dimethyl disulfide).
From: Direct sulfuric acid formation from the gas-phase oxidation of reduced-sulfur compounds
The scheme focuses on the reaction steps relevant for the formation of H2SO4 and MSA (methane sulfonic acid) starting from CH3S and CH3SO2 and is mainly based on Barnes et al.9. Signals of observed products in the present study are shown in bold. Dashed red arrows indicate complex reactions to the stated intermediates. Only important main products of the individual pathways are displayed.
