Considering the current literature, studies using SEM analysis to determine the reactions and transformation of TMCS are very limited. It is known that trimethylchlorosilane (TMCS) molecules convert to bis(trimethylsilyl) ether (hexamethyldisiloxane, HMDSO) upon contact with moisture. The conversion process of TMCS to HMDSO was observed using SEM. EDX analysis confirmed that no contaminants were present on the surface, except for TMCS and HMDSO molecules. To monitor the reaction, samples containing TMCS were incubated for 8 to 24 h at room temperature under both humid and non-humid conditions. The molecular images and reaction stages observed during this process were meticulously documented. The SEM-EDX analysis, along with the contribution of the targets, shows significant potential for adding unique value to the literature. It is clear that the literature needs the innovative perspective and contributions that our study provides. A clear determination of the conversion of TMCS to ether in a controlled humidity environment has been made. The most important conclusion is that the validation of these results, both at the elemental level and through SEM analysis, demonstrates that this is an efficient experimental process. This method holds significant potential for application in various multidisciplinary fields, including industrial analysis and chemical reaction monitoring.
