摘　　要：以鄂东钙基蒙脱石提纯、钠化后(d001=1.28 nm)为基质原料,用钛酸正丁酯[Ti(n-C4H9O)4]为钛源,采用溶胶-凝胶法制备了一系列钛交联蒙脱石纳米复合材料(Ti-PILCs);并对水/丙酮比、Ti/土比、交联反应时间、不同溶剂等制备条件进行了分析,试验条件下,可获得d001值达3.74 nm的大孔结构Ti-PILCs高纯蒙脱石复合材料。A Ti -pillared montmorillointe （Ti -PILC） has been synthesized by using the purified and sodium modified Ca -montmorillonite and n -butyl titanate [ （n -C4H9 O）4 ] by the sol -gel process. Several parameters in the synthesis such as water/acetone ratio, Ti/montmorillonite ratio, cross- linking time, solvent etc, have been investigated. Under the optimum conditions, Ti - PILCs with the value of d001 of 3.74 nm was prepared.
