摘    要:用X射线衍射方法对不同柱撑浓度条件下制备的HDTMA^ 柱撑蒙脱石系列样品进行研究,结合有机离子的理论空间几何尺寸,提出有机柱撑离子在层间的不同排列展布方式。水平单层排列的HDTMA^ 离子可以有两种不同的排列方式并分别对应于柱撑产物的不同底面间距,水平双层排列虽然也可形成两种不同的排列方式,但是柱撑产物具有相同的底面间距,并用联锁嵌合结构解释了有机离子在水平双层和假三层排列模式下其实际总体高度要低于各单层高度数字之和。

关 键 词:蒙脱石  有机柱撑  HDTMA’  几何尺寸  排列方式

Abstract:The relationship between the orientations of HDTMA~+ in the interlayer of organic pillared montmorillonites prepared at different concentrations and its theoreticaize have been studied using X-ray powder diffraction (XRD) and theoretical size. Several arrangement models of HDTMA~+ in the interlayer of montmorillonite have been proposed. Two kinds of arrangement that correspond to different basal space were revealed as the arrangement of lateral monolayer, and two kinds of arrangement with the same pillared height were supposed as the arrangement of lateral bilayer too. The reason that the practical heights of lateral-bilayer and pseudotrilayer arrangement were smaller than the value adding by each single alkyl-chain was explained through the interlocking structure.
Keywords:montmorillonite  organic pillared  HDTMA~+  theoretic size  arrangement
