Pyrolyses in the presence of nitric oxide. Part III. Acetaldehyde oxime and nitrosoethane

The pyrolysis of acetaldehyde oxime in the presence of nitric oxide has been studied between 240 and 280 °C. The pyrolysis of nitrosoethane alone and with nitric oxide has been studied between room temperature and 120 °C. The results are shown to accord with the mechanisms predicted for these pyrolyses. They agree in essence with those proposed for the high-temperature pyrolyses of ethane and n-butane in the presence of nitric oxide, in which the oxime and nitroso-compounds are involved as unstable intermediates, although the lower temperature reactions are complicated by heterogeneous processes.
