Zusammenfassung
Hydroxylamine is a key molecule for some important chemical processes. An example is the synthesis of ε-caprolactam, which is required for the production of Nylon. Since hydroxylamine decomposes thermally, its transport and storage are problematic. It is also problematic for the synthesis of hydroxylamine from ammonia with titanium silicalite-1.
The goal of this study was to investigate the exothermic decomposition reaction. The heat of the reaction was measured in multiple DSC experiments. During the decompo sition, vast quantities of gases are released. To measure the pressure rise, an explosion reactor was employed. Three reaction hypotheses have been tested. With the use of a
mathematical model one hypothesis could be proven. The material in uence on the de composition reaction was examined for PEEK, stainless steel and hastelloy C22. From the DSC measurements, a descriptive model and isoconversional kinetics were obtained.
