Hydrogen Pressure and Temperature Effect on the Rate of Nitrobenzene Hydrogenation over Skeleton Nickel in a Liquid Phase

The kinetic model for reductive alkylation of aniline with acetone using 30 wt % Ni/Organoclay was derived and validated at different temperatures. The catalyst was synthesized and characterized for structural and morphological properties, showcasing promising potential in organic synthesis due to the synergistic effects of nickel on organoclay. As per our knowledge, no one reported the reductive alkylation of aniline using Ni/ Organoclay. Additionally, very few articles are reported on the kinetic modeling of this reaction. To address this gap, we have investigated the kinetics of reductive alkylation of aniline with acetone using a Ni/ Organoclay catalyst. The study systematically investigates the influence of various reaction parameters, such as temperature, pressure, catalyst screening, concentration of the catalyst, mole ratio, agitation speed, and reactant concentrations, on the reaction kinetics. The kinetic analysis involves the determination of crucial parameters, such as reaction rate, activation energies, and heat of adsorption. A number of rate equations were derived to fit the batch reactor data, and rate models based on Langmuir−Hinshelwood competitive associative adsorption of the surface reaction between the Schiff base and hydrogen as the rate-limiting catalytic steps were found to represent the experimental data.
