利用ＸＲＤ，ＴＰＤＥ，ＴＰＤ和ＴＧＤＴＡ等为主要研究手段，深入分析了Ｚｒ（ＳＯ４）２·４Ｈ２Ｏ的层状结构特征和插层性能，并以乙酸与乙二醇单醚的酯化反应为目标反应考察了其催化性能．研究结果表明：Ｚｒ（ＳＯ４）２·４Ｈ２Ｏ是一种具有中等强度酸性的层状化合物，位于层间的结晶水是产生Ｂ酸中心的来源；有机胺类分子具有较强的插层能力，胺的插入可将层板撑开并使层间距增大，从而进一步证实存在层间结晶水所产生的Ｂ酸中心；Ｚｒ（ＳＯ４）２·４Ｈ２Ｏ的催化活性来源于其独特的层状结构及位于层间的Ｂ酸位 Using XRD, TPDE, TPD and TG-DTA as the main research methods, the lamellar structure and intercalation properties of Zr (SO4) 2.4H2O were deeply analyzed. The esterification reaction of acetic acid with ethylene glycol monoether was The target reaction investigated its catalytic performance. The results show that Zr (SO 4) 2 · 4H 2 O is a kind of layered compound with moderate acidity. The crystal water located between the layers is the source of B acid. The organic amines have strong intercalation ability. Amines The intercalation of the interlayer could increase the interlayer spacing and further confirm the presence of B acid in the interlayer water. The catalytic activity of Zr (SO4) 2 · 4H2O is derived from its unique layered structure and at B acid level between layers
