| 摘 要： | 用原位合成法,以酸性Al2O3为载体,酞菁类金属大环配合物为活性组分,合成出CoPc/Al2O3新型环氧化催化剂,红外、紫外-可见、热重分析及XPS证实能够利用该法在Al2O3上固载CoPc催化剂,且催化剂稳定性增加,不易流失.以分子氧为氧源,异丁醛为共还原剂考察CoPc/Al2O3催化剂对环己烯的催化环氧化活性及催化剂的重复使用情况.结果表明,与均相催化剂相比,固载后环己烯转化率增加了8%,环氧环己烷选择性增加了23%,催化剂重复使用4次后,活性仅降低4%.

| Abstract: | CoPc complex was supported on the acid alumina using in-situ method.The resulting compounds were characterized by DTA-TGA thermal analysis,ICP,XPS,solid-state infrared and Ultraviolet/visible spectroscopy and tested as catalysts for the oxidation of cyclohexene under ambient conditions using molecular dioxygen as oxidant and isobutyraldehyde as sacrificial reagent.The supported catalyst showed higher activity than the neat complex.The conversion of cyclohexene increased 8% and the selectivity increased 23%.In addition,its catalytic activity only decreased 4% after the catalyst was reused 4 times. |
