Resumen:
The effect of solvent on Ni(10.5%)/SiO2 activity and selectivity for the liquid-phase hydrogenation of butyronitrile to butylamines was studied at 373 K and 13 bar using ethanol, benzene, toluene and cyclohexane as solvents. In ethanol, a protic solvent, the Ni catalyst yielded n-butylamine (84%) and dibutylamine. When non-polar solvents such as cyclohexane, toluene or benzene were used, the solvent-catalyst interaction strength determined the selectivity to n-butylamine: the stronger the solvent-catalyst interaction the higher the n-buylamine production. The yield to n-butylamine in nonpolar solvents varied between 39% (cyclohexane) and 63% (benzene).
