<p>A nitrosation of secondary amines performs in liquid-gas system by nitrating gases comprising nitrogen oxides of structure N2Ox, wherein "x" is nitrogen oxidation degree, which can be range from 2 to 4 (2.5 - 3), at a temperature of from 0 to 60 °C (10 to 35 °C), at partial pressure of nitrogen oxides of from 0.001 to 0.6 MPa, in the presence of liquid phase or without a presence thereof at the beginning of process, in the presence of nitric acid neutralized compounds and/or compounds easily oxidized or nitrated, thereby ensure reduction of concentration of nitric acid and amount of supplementary reactions consuming amine or derivative thereof.</p> |
