FIELD: chemistry.
SUBSTANCE: installation for obtaining nitrogen oxide by direct oxidation, including pipelines for nitrogen and oxygen supply, plasma chamber with connecting pipes for gas input and output, unit of gas mixing, differs by the following: unit of mixing is made in form of tube mixer formed by two transverse partitions joined to introduced between them longitudinally placed branch pipes which have canals in walls. To part of pipeline, located between partitions and involving space between branch pipes, pipeline of other gas is joined, diametre of openings do in input partition, as well as quantities and diametres of branch pipes d1 and canals of diametre d2, drilled in walls of tube mixer branch pipes, are taken on the assumption of condition of achievement of injective mixing of nitrogen with oxygen obtaining nitrogen-oxygen mixture of equimolar composition.
EFFECT: increase of stability of composition of coming out reaction gases, increase of target product yield.
