钛交联蒙脱石纳米复合材料的制备及其酸催化性能初探

Preparation of Ti-Cross-linking Montmorillonite Nanocomposite and Preliminary Research on Its Acid Catalysis Performance

以鄂东某地钙基膨润土提纯钠化改型后得到的高纯钠基蒙脱石为基质,采用溶胶-凝胶法制备了钛交联蒙脱石纳米复合材料,然后将之作为固体酸催化剂应用于合成二芳基乙烷的Friedel-Crafts烷基化探针反应中,初步探讨了钛交联蒙脱石纳米复合材料的酸催化性能,为其在固体酸催化领域的应用提供了借鉴。

A Ca-bentonite ore from the east part modified, preparing an ultrapure Na-montmorillonite. of Hubei Province had been beneficiated and sodium The Na-montmoriUonite was used as matrix. A Ticross-linking montmorillinite nanocomposite had been prepared by sol-gel process. Then, the Ti-crosslinking montmorillinite nanocomposite served as solid acid catalyst was used in Friedel-Crafts probe reaction to synthesize diaryl ethane, Acid catalysis performance of the Ti-eross-linking montmorillinite nanocomposite was studied preliminarily, which gave a reference to its application in the field of solid acid catalysis,
