Abstract

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 × 10⁻⁴ to 11.12 × 10⁻⁴ mol/L, the temperature in the range from 160 to 190°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.
