摘　　要：将MgAl水滑石引入到金属四苯基卟啉(MTPPs,M=Co,Fe,Mn,Ni)催化氧化体系中,实现了醇的选择性氧化。结果表明,在分子氧/异丁醛体系中,CoTPP在苯甲醇氧化制苯甲醛反应中表现出优异的催化活性,MgAl水滑石添加剂可有效地提高醛的选择性。在苯甲醇1 mmol、乙腈2 mL、CoTPP 5 mg、MgAl水滑石18 mg、异丁醛5 mmol、反应温度60℃、氧气气氛下反应2 h,苯甲醇的转化率和苯甲醛的选择性分别达到94%和92%。另外,此催化体系在其它醇类化合物的氧化反应中也具有较好催化活性。The selective aerobic oxidation of alcohols to carbonyl compounds was achieved by introduction of MgAl hydrotalcite into the metallotetraphenylporphyrins(MTPPs,M=Co,Fe,Mn,Ni)catalytic oxidation system.The results indicated that CoTPP exhibited the highest catalytic activity in the oxidation of benzyl alcohol to benzaldehyde through molecular oxygen/isobutyraldehyde(IBA)system,and MgAl hydrotalcite additive could effectively improve the catalytic selectivity of aldehyde.Under the optimized conditions(benzyl alcohol 1 mmol,acetonitrile 2 mL,CoTPP 5 mg,MgAl hydrotalcite 18 mg,IBA 5 mmol,reaction temperature 60℃,oxygen atmosphere,reaction time 2 h),the conversion of benzyl alcohol and the selectivity of benzaldehyde reached 94%and 92%,respectively.The catalytic system also exhibited good catalytic performance in the oxidation of other benzylic alcohols.
