| 摘 要： | 利用溶剂化作用,将辛胺和正硅酸四乙酯同时插层进入十六烷基三甲基有机阳离子型蒙脱石层间,在辛胺的碱性催化作用下,正硅酸四乙酯在蒙脱石层间原位水解得到硅酸及有机物混合插层蒙脱石.将此混合插层化合物在550℃煅烧后得到硅柱撑蒙脱石.用TG-DTA、XRD、TEM和N_2吸附-脱附等技术对所制备的硅柱撑蒙脱石进行了表征.结果表明:蒙脱石经硅柱撑后其比表面积由原始的80m~2/g增大到667m~2/g,孔容达到0.7413cm~3/g,具有介孔结构.

| Abstract: | Silica-pillared montmorillonite with microporous and mesoporous pores was prepared by interlamellar hydrolysis of tetraethyl orthosilicate catalyzed by n-octylamine after solvation of n-octylamine and tetraethyl orthosilicate with cetyl trimethylammonium in the interlayers of montmorillonite. The characteristics of pillared clay were examined by TG-DTA, XRD, SEM, TEM and N2 adsorption-desorption methods. Results indicated that the specific surface area and pore volume were all increased obviously compared w... |
