The Synthesis of A New Metallomicellar Oxidase Model and Catalytic Oxidation of Benzyl Alcohol

通过酯化、Fries重排、磺化、缩合、络合等反应,首次合成并表征了席夫碱型双亲性配体及其Cu( )配合物,合成总产率为24.5%;测定了配体及配合物在水溶液中的表面张力(最低分别为30和36mN/m)及临界胶束浓度(分别为6.2×10-4和2.5×10-3mol/L);考察了配合物在稀碱溶液中催化苯甲醇的空气氧化作用:在40℃、10%NaOH溶液中,配合物催化苯甲醇空气氧化生成苯甲醛的产率达到57.8%,表明该配合物具有较好的双亲媒性和较高的催化空气氧化苯甲醇的性能.

A new amphiphilic Schiff base ligand, N, N'\| bis droxy3su ethylene diimine and its Cu(Ⅱ) complex was firstly synthesized and characterized. The total synthetic yield of the complex was 24.5% after the reactions of esterification, Fries rearrangement, sulfonation , condensation and coordination. According to the determination, the surface tensions of the ligand and complex are 30 mN/m and 36mN/m, and their critical micelle concentrations are 6.2×10-4 mol/L and 2.5×10-3 mol/L respectively. The air oxidation of benzyl alcohol catalyzed by the complex in water solution were also investigated. Benzaldehyde was prepared from the oxidation of benzyl alcohol catalyzed by the complex at yield of 57.8% in 10% NaOH at 40 ℃.The experiment result showed that, the complex have amphiphilic property and well performance for catalyzing air oxidation of benzyl alcohol.
