The effects of acetone on the hydrogenation of diisopropylimine (DIPI) over Ni catalysts were studied. Microcalorimetric adsorption and infrared spectroscopy were employed to determine the surface bond strengths and structures of related species adsorbed on Ni. The results demonstrated that acetone was hydrogenated to isopropanol that accelerated the hydrogenation of DIPI. Since the acidic support promoted the hydrogenation of acetone on Ni, Ni/Al₂O₃ was more favorable than Ni/LaAlO for the increase of activity for the hydrogenation of DIPI in the presence of acetone.

丙酮对负载型镍催化剂上二异丙基亚胺加氢的影响

研究了丙酮对Ni催化剂上二异丙基亚胺（DIPI）加氢的影响。用微量热吸附和红外光谱法测定了镍上吸附的相关物质的表面结合强度和结构。结果表明，丙酮被氢化为异丙醇，从而加速了DIPI的氢化。由于酸性载体促进了丙酮在Ni上的氢化，因此Ni / Al ₂ O ₃比Ni / LaAlO更有利于增加丙酮存在下DIPI的氢化活性。
