“…At 25 • C, the density of MOS is 0.975 ± 0.005. When the temperature drops to 20 • C, the relative density of MOS increases to 0.982 [34]. When exposed to heat, MOS will decompose and release nitrogen oxide (NO x ), silica, carbon dioxide, carbon monoxide, butanone, and possibly MEKO.…”

“…Common MOS production processes currently include titration processes, transesterification [39], carboxyl exchange, and sodium metal synthesis. Due to the high production costs, the difficulty in obtaining raw materials, the complexity of the production process, and the low safety coefficient of the latter three processes, the methods are rarely used in industrial production [34].…”

Chemical safety accidents caused by the thermal runaway of materials occur frequently around the world, seriously hindering the sustainable development of the chemical industry. Therefore, studies related to the thermal safety of materials are very important for chemical production. In order to ensure the safety of methyl tris (methyl ethyl ketone oxime) silane (MOS), the thermal safety of its accident-prone by-product, methyl ethyl ketone oxime hydrochloride (MEKOH), was analyzed in the study. Temperature changes of MEKOH dissolved in 5%, 10% and 15% deionized water were measured with the flask method. Thermogravimetric (TG) analysis and differential scanning calorimetry (DSC) were applied to comprehensively analyze the thermal stability of MEKOH in different reaction states. The thermal decomposition products of MEKOH were detected with gas chromatography-mass spectrometry (GC-MS). The results show that the temperature of MEKOH dissolved in deionized water at room temperature (28 °C) increases by about 5 °C, and finally stabilizes at 33 °C. MEKOH has good thermal safety during this process. When the temperature rises to 50 °C, MEKOH starts to decompose violently, and no longer exhibits significant weight loss at 145 °C. From 50 °C to 100 °C, MEKOH releases heat, ranging from 29.65 to 45.86 J/g, during thermal decomposition, generating a large amount of flammable substances. The thermal decomposition products were detected, including pyrrolidine, heptane, MEKO, and other substances, but no MEKOH was detected. Overall, the study provides a theoretical basis for preventing the thermal runaway of MEKOH.
