SYNTHESIS OF MESOPOROUS MOLECULAR SIEVE VMCM-41 BY MICROWAVE RADIATION AND ITS CHARACTERIZATION

以溴代十六烷基吡啶（ＣＰＢｒ）为模板剂，硅溶胶为硅源，用微波辐射的方法成功地合成出了高结晶度的中孔杂原子ＶＭＣＭ－４１分子筛，探讨了微波反应釜压力、微波晶化时间、老化时间等合成因素的影响，确定了合适的配比范围及合成条件。利用ＸＲＤ、ＴＥＭ、ＩＲ等方法对ＶＭＣＭ－４１中孔分子筛的结构作了表征。

In this paper, the synthesis of a new vanadium-containing mesoporous molecular sieve VMCM-41 with cetylpyridinium bromide as templating agent by means of microwave radiation is reported The synthesis conditions suchasi ageing time, crystallization time, pressure, feedstock proportion and the experimental parameters have also been evaluated The micro-structure of the crystal and property of the phases in the molecular sieve were studied by means of XRD, IR and TEM techniques It was confirmed from the IR spectra that titanium atoms have been located into the framework of the molecular sieve
