摘要：

A series of Cu-based catalysts were prepared and examined for the reductive amination of triacetoneamine with n-butylamine, thereinto, Cu-Cr-La/gamma-Al2O3 showed excellent results. The catalysts were studied by XRD, XPS, H-2-TPR and NH3-TPD. It was found that doped Cr remarkably enhanced the activity of Cu/gamma-Al2O3 due to better dispersion of Cu-0, which is believed to be the active site for the reductive amination. Additionally, it was obvious that introduction of La to Cu-Cr/gamma-Al2O3 led to a higher selectivity and longer lifetime. The reaction parameters were optimized and N-butyl-2,2,6,6-tetramethyl-4-piperidinamine was obtained in a yield of 94%.
