摘要：

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(NO3)(2)center dot 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.
