摘要/Abstract

摘要： 以羟基铝低聚物与其交联制得柱撑皂石,并在偏三甲苯歧化反应中考察了它们的催化性能.结果表明,催化活性随柱撑皂石表面酸量增加而增加;四甲苯中均四甲苯和二甲苯中邻二甲苯的百分含量皆高于热力学平衡值.催化特性与柱撑皂石的柱密度相关.

关键词: 柱撑皂石, 偏三甲苯歧化, 择形性

Abstract: The pillared saponite elays(PS) were prepared by cross-linking the saponitc with aluminium hydrxy polymer [Al₁₁O₄(OH)₂₄·(H₂O)₁₂]³⁺ The catalytic properties of saponite and their pillared analogues were investigated during the disproportionation reaction of 1,2,4-trimethylbenzene.Te results show that the catalytic activity increases with increasing the acidic amount on the surface of PSand the percent of 1,2,4,5-Te MB in Te MB and of o-xylene in xy-lene are higher than their values of thermodynamic equilibrium respectively.The catalytic property which is related to the pillar density in the PS

Key words: Pillared saponite, Disproportionation of 1,2,4-trimethylbenzene, Shape selectivity
