摘要：
The continuous synthesis of bis[3-(dimethylamino)propyl]amine (BPA) by hydrogenation of 3-(dimethylamino)propionitrile (PN) in the presence of 3-(N,N-dimethylamino)propylamine (PA) over copper-based catalysts was investigated. It was found that Cu-Cr2O3-CoO/gamma-Al2O3 yielded satisfactory results with almost 100% PN conversion and 88.5% BPA selectivity (H-2 pressure: 1 Mpa, temperature: 100 degrees C, PN/PA ratio: 2:1). All catalysts were characterized by XRD, XPS, H-2-TPR, and TEM, the obtained results indicated that Cr could improve the catalytic activity. Moreover, Co dispersed around Cu particles promoted the catalytic nature, which could further enhance the activity and stability of the catalyst.
