作者： PAN Chun-liu ZHANG Wen-xiang LI Xue-mei JIANG Da-zhen wu tong-hao College of Chemistry Jilin UniversityChangchun 130023P.R.China

Three titanium-containing aluminum phosphate catalysts with a general formula Al 0.77 Ti 0.23 PO 4 were prepared by the sol-gel method at room temperature(APTS), and a nonuniform precipitation procedure at room temperature(APTR) and under reflux(APTF), respectively. The structural features and the surface properties of the three catalysts were determined by means of the physical adsorption of nitrogen at liquid N 2 temperature, XRD, UV-Vis, NH 3-TPD and IR of adsorbed pyridine. The vapor phase O-alkylation of catechol with ethanol over the prepared catalysts was studied. It was found that the activity and the selectivity of these catalysts are greatly dependent on the preparation method, and catalyst APTF shows the highest activity and selectivity. The characterization evidence indicates that the weak Brnsted acid sites were more effective for the reaction.

作者： Zhao Yu-sheng, HUA Shi-ying , wu tong-hao and WEI Quan (Department of Chemistry, Jilin University, Changchun, 130023) Worked in Institute of Theoretical Chemistry, Jilin University, Changchun.

The homogeneous system of 12-tungstophosphoric acid and diethylene glycol was studied using IR and NMR spectra. It was found that the protons in 12-tungstophosphoric acid formed proton oxonium ions with the hydroxyl oxygen in diethylene glycol by hydrogen-bonds, and the formed proton oxonium ions could react with the terminal oxygens of heteropoly anions. The dehydration-cyclization mechanism of diethylene glycol in the presence of heteropoly acid was also proposed.

Up till now, the crosslinking agent used in the preparation of highcrosslinking polystyrene has usually been divinylbenzene(DVB), which usually results in the crosslinking net structure of styrene-DVB copolymer being uneven. On the contrary, bisvinyl-A has the well compatibility with styrene,which can polymerize to form an even copolvmer, this copolymer has well

以不同分子筛(Nonasil,MCM-22或MCM-49)为晶种,在水热条件下以六亚甲基亚胺(HMI)为模板剂,对纯硅沸石Nonasil(HMI)的合成进行了研究.并且对各种合成参数,包括晶种类型、硅源、晶化温度和Na+浓度等对Nonasil(HMI)合成的影响进行了探讨.发现在适量的Na+存在条件下,晶种的引入大大缩短了晶化时间;不同类型的晶种对晶化速度有不同程度的提高.特别是用异类晶种(如MCM-22或MCM-49)能够合成高结晶度的Nonasil(HMI).
