AbstractMeasurements of a hydrogen solubility in various nitrobenzene-aniline mixtures were conducted in an autoclave reactor with a stirrer and control of temperature. The solubility of the hydrogen was measured under 7 different values of temperature (30°C, 40°C, 50°C, 90°C, 130°C, 170°C, 210°C), 3 values of a stirrer rotation speed (1200 rpm, 1600 rpm, 2000 rpm) and range of pressure 20÷30 bar. Moreover, pure aniline, pure nitrobenzene and their mixtures with different concentration were used. In the next step values of Henry’s constant were calculated. Based on an experimental data dependence of Henry’s constant on temperature for pure aniline and pure nitrobenzene was proposed. Additionally, for each temperature correlations between Henry’s constant and aniline’s concentration in mixture nitrobenzene-aniline were found.
