摘　　要：采用等体积浸渍法经程序升温焙烧制备了Cu/SiO2催化剂,考察了该催化剂对苯胺和正丙醇气相合成N-丙基苯胺的催化活性和选择性.常压下,当反应温度为260℃时,Cu/SiO2上正丙醇转化率达到100%,N-丙基苯胺选择性超过92%.X射线衍射分析表明,该催化剂具有较好的铜结晶度.N-propyl aniline was efficiently synthesized in vapor phase from aniline and 1-propanol at atmospheric pressure over the Cu/SiO2 catalyst that was prepared by the incipient wetness method and temperature-programmed calcinations. The catalyst exhibited very high activity and selectivity. At the reaction temperature of 260 ℃ , 1-propanol conversion reached 100%, and the selectivity for N-propyl aniline exceeded 92%. The resuits of X-ray diffraction showed that the Cu/SiO2 catalyst with high catalytic activity and selectivity had good crystallinity of copper.
