| 摘 要： | 以离子液体1-十六烷基-3-甲基溴代咪唑为模板剂合成了Al-MSU-S-Y介孔分子筛,利用XRD、N2吸附-脱附对其进行结构表征,结果表明该方法合成的样品具有较大的孔径、孔容以及比表面积,而且孔径分布较窄.研究了Al-MSU-S-Y对乙二醇与环己酮、丁酮、丙酮、丙醛、丁醛、异丁醛、戊醛、异戊醛、正己醛、正辛醛、苯甲醛等十余种醛(酮)的缩合反应的催化性能,结果表明Al-MSU-S-Y介孔分子筛对醛(酮)与醇的缩合反应有较好的催化性能.

| Abstract: | Mesoporous molecular sieves Al-MSU-S has been prepared from the precursor of Y zeolite using 1-hexadecane-3-methyl-imidazolium bromide(CMIMB) as a template in basic medium,which exhibited larger pore diameter,pore volume and surface area.The catalytic activity of Al-MSU-S-Y was studied via the acetalization and ketalization of different aldehydes and ketones with glycol.Results showed that it was an efficient catalyst for the synthesis of acetals(ketals). |
