Catalytic ammonia oxidation to nitrogen (I) oxide [PDF]

open access: yesAustrian Journal of Technical and Natural Sciences, 2015
The process of synthesis of nitrous oxide by low-temperature catalytical oxidation of NH has been investigated for organic synthesis. The investigation has been carried out by the stage separation approach with NH oxidation occurring in several reaction zones, which characterized by different catalytic conditions.
