Abstract
A method for the preparation of nitrogen oxides (NO+NO) comprises the oxidation of nitrogen oxide with intermediate products of thermal decomposition of nitric acid. For decreasing of temperature, increasing of concentration of nitrogen oxides (NO+NO) and decreasing reaction mixture volume nitrogen oxide is mixed with nitrogen oxide (IV) and said mixture is exposed to irradiation of ultraviolet lamp.
