通过水热法及沉淀法,合成了纳微尺度铜金属有机框架催化剂.通过FT-IR、TG及TEM等技术手段对其性能和结构进行了表征.系统考察了催化剂、溶剂种类及用量、反应时间等因素对异丁香酚氧化制备香草醛的影响.结果表明,用均苯三甲酸根(BTC)作配体时制备的催化剂Cu-BTC性能较佳.以Cu-BTC为催化剂、30％(质量分数)H2 O2为氧化剂、乙腈为介质,当n(异丁香酚)∶n(H2O2) =1∶2.4时,50℃,反应8h,异丁香酚转化率为94.4％,香草醛产率达到81.8％.纳微尺度(粒径30 ～ 300 nm) Cu-BTC催化剂体现了良好的重复使用性能,连续反应5次,异丁香酚转化率保持在90％左右.
