Combining Ni3P and Lewis Acid-Base Pair as a High-Performance Catalyst for Amination of 1-Octanol

Ni phosphide and Lewis acid-base pair site of Al2O3 were combined as highly efficient catalyst for direct amination of 1-octanol to 1-octylamine. Due to the higher dehydrogenation activity and the site isolation effect, Ni3P/Al2O3-TPP prepared by organophosphorus was 4.0 times more active than Ni/Al2O3 and increased the selectivity to 1-octylamine from 71.4 to 92.8% at 0.4 MPa NH3.
