The catalytic hydrogenation of nitrile esters to amino esters was studied.Amino-esters are alternative monomers to produce these polymers. The hydrogenation of nitrile ester was performed in a stirred tank reactor. The mixing of the fluids was carried out using a gas induction stirrer with a hollow shaft. An appropriate amount of ammonia has to be dissolved into the reaction mixture in order to avoid side or consecutive reactions, whereas the starting material nitrile ester was diluted by applying methyl-cyclohexane as solvent.The influence of the amount of dissolved ammonia and the hydrogen solubility in the reactants and in the chosen solvent were considered in this study. A reaction mechanism is proposed a mathematical model, which describes the proposed reaction mechanism of intermediate species and products was proposed for this hydrogenation reaction. The data were fitted using the least square method and the relevant kinetic rate constants were determined.

Utilization of Catalytically Active Foams for Enhancing Energy Efficiency in Chemical Reactors.
Lali, Farzad
In the present study a tubular reactor that was packed with a Pd/Al2O3 foam packing with a length of 50 cm and a diameter of 1.8 cm. The hydrogenation of α-methylstyrene (AMS) to cumene was\nemployed for characterization of the reactor performance due to availability of literature data for other reactor types that facilitated a comparison.
