Investigation into diffusion nitrogen oxides at atmospheric pressure in the temperature range 290-370K

The experimental data on diffusion coefficients of N2O4 with nitrogen and its oxides with atmospheric pressure in the range of temperatures 290-370 K in the gas phase have been obtained by the method of a double-flask apparatus. The double-flask apparatus implements quasi-stationary diffusion on investigated gases through the capillary (the set of the capillaries) from one volume to the other, so the analysis of gas mixture after diffusion in both flasks is necessary in all cases. The analysis of the mixture composition after diffusion has been conducted by the modernized chromatograph. The error of the measured diffusion coefficients falls within the limits of 2-10%
