摘要
采用X射线粉末物相分析、红外及紫外漫反射光谱、差热分析、NH3脱附法和气体吸附等测试手段研究了TiSi沸石TS1,TS2,TiZSM48及钛酸钠、钛铝酸钠和钛酸铜分子筛的性能和结构.利用苯酚羟基化反应证明了含有TiO4四配位结构单元的沸石分子筛具有催化氧化活性.考察了各种实验条件对苯酚羟基化反应的影响.
The structure and physicochemical properties of zeolites TS1, TS2, TiZSM48, sodium titanate, copper titanate and sodium titanoaluminate were studied by using the methods of XRD, IR, UVVIS, DTA, NH3TPD. It was proved that the zeolites in which having the structural unit of four coordination TiO4 show catalytic activity for the reaction of phenol hydroxylation. Influence of experimental conditions on the reaction of hydroxylation were also investigated in detail.
