Selective gas-phase hydrogenation of benzonitrile into benzylamine over Cu-MgO catalysts without using any additives

A clean and mild gas-phase hydrogenation of benzonitrile to benzylamine has been accomplished using Cu-MgO catalysts prepared by impregnating a freshly prepared MgO support using Cu(NO 3 ) 2 ·3H 2 O as a Cu precursor with Cu loading of 4, 8, 12 and 16%, of which 12% Cu-MgO catalyst exhibited superio...

Description
Summary:A clean and mild gas-phase hydrogenation of benzonitrile to benzylamine has been accomplished using Cu-MgO catalysts prepared by impregnating a freshly prepared MgO support using Cu(NO 3 ) 2 ·3H 2 O as a Cu precursor with Cu loading of 4, 8, 12 and 16%, of which 12% Cu-MgO catalyst exhibited superior activity with 98% conversion of benzonitrile and 70% selectivity of benzylamine even in the absence of any additives at atmospheric pressure. Under these optimized conditions, the selectivity of benzylamine has been significantly elevated to nearly 100% with considerable conversion. A clean and mild gas-phase hydrogenation of benzonitrile to benzylamine with 100% selectivity at conversion levels of 50-60% over 12% Cu-MgO catalyst.
