Catalytic amination of 2,6-dimethylphenol to 2,6-dimethylaniline over Ni–Cu–Cr/γ-Al2O3

Catalytic amination of 2,6-dimethylphenol to 2,6-dimethylaniline over Ni–Cu–Cr/γ-Al2O3 A series of transition metal-based catalysts, other than Pd or Pt-based catalysts, were investigated for catalytic amination of 2,6-dimethylphenol to 2,6-dimethylaniline in a fixed-bed reactor. Ni–Cu–Cr/γ-Al2O3 yielded satisfactory results with 82.08 % conversion and 47.24 % selectivity. The catalysts were characterized by H2-TPR and TEM, and the results obtained showed that the doped Cu and Cr could promote reduction of Ni/γ–Al2O3 and dispersion of the Ni. Reaction conditions, including reaction temperature, flow rate of hydrogen, and ammonia, were studied. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals
