摘要：
The results are presented from studying the catalytic properties of ruthenium catalyst 3% Ru/MN270 based on hypercrosslinked polystyrene in the reaction of three-phase hydrogenation of nitrobenzene to aniline. The following parameters are varied in the study: the NB concentration in the range from 0.12 to 0.24 mol/L, the catalyst concentration in the range from 1.11 x 10(-4) to 11.12 x 10(-4) mol/L, the temperature in the range from 160 to 190 degrees C, and the partial hydrogen pressure in the range from 1.013 to 0.113 MPa. The optimum parameters of the process are determined, allowing 97% conversion of nitrobenzene and a selectivity of 98% towards aniline to be achieved.
