摘　　要：以硝酸铜和Al_2O_3为原料,采用浸渍法制备了一系列Cu O/Al_2O_3催化剂,用于甘油的催化氧化。系统研究了:Cu O/Al_2O_3的铜含量、反应温度、Na OH/甘油的物质的量之比、催化剂用量、反应时间对甘油催化氧化的影响,结果表明:Cu O/Al_2O_3可高效氧化甘油为甘油酸和羟基乙酸。最佳条件为:O_2流量80 m L/min,氢氧化钠/甘油=8,60℃反应8 h,甘油的转化率为65.3%,甘油酸的选择性48.1%。A series of Cu O/Al_2O_3with different Cu content were synthesized by impregnation method and applied in the selectively oxidation of glycerol.The reactive factors such as the content of copper of Cu O/Al_2O_3,temperature,the molar ratio of Na OH/glycerol,the amount of catalyst and react time were systematically investigated.The optimum reaction conditions were as follows：80℃,Na OH to glycerol molar ratio of 8,oxygen 80 m L/min,react 8 h,glycerol conversion of 65.3%,glycelic acid selectivity of 48.1%.
