The kinetics of catalytic hydrogenation of nitrobenzene in the presence of Ru-containing catalysts
Journal Title: Бюллетень науки и практики - Year 2018, Vol 4, Issue 12
Abstract
The process of catalytic hydrogenation of nitrobenzene is the most important chemical and technological process of obtaining aniline, which is used as a semi-product in the synthesis of polyurethanes, rubbers, various pharmaceuticals, pesticides, and herbicides. The paper presents the investigation of the kinetics of catalytic hydrogenation of nitrobenzene to aniline in the presence of Ru–containing catalysts based on hypercrosslinked polystyrene. Nitrobenzene hydrogenation reaction was carried out in a six-point high-pressure steel reactor Series 5000 Multiple Reactor System (MRS). As a catalyst, 3% Ru was used on the basis of hypercrosslinked polystyrene of the brand MN 270 (Purolite Ltd, UK). Experiments aimed at studying reaction kinetics were carried out in the work. Product analysis was performed by gas chromatography using a gas chromatograph Crystallux-4000M (Russia, Meta–Chrome). Was chosen the optimal parameters of the reaction. A kinetic reaction model was also proposed.
