Verfahren zur Herstellung von Hydroxylaminen aus Ammoniak oder den entsprechenden Aminen, Wasserstoff und Sauerstoff

摘要

A method is proposed of producing hydroxylamines from ammonia or the associated amines, hydrogen and oxygen. The method involves the reaction by heterogeneous catalysis of the initial materials; for this purpose, use is made of an oxidation catalyst based on titanium- or vanadium silicates with a zeolitic structure and comprising 0.01-20 wt.% platinum-group metals selected from the group ruthenium, rhodium, palladium, osmium, iridium and platinum, these metals being present in at least two different bonding energy states.
