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.
Pillared saponite was prepared by the cross-linking of Al (OH) 2 oligomers and their catalytic properties were investigated in the disproportionation of p-trimethylbenzene.The results showed that the catalytic activity increased with the increase of acid content on the surface of p-saponite. The percentages of ortho-xylene in both mesitylene and xylene were higher than the thermodynamic equilibrium values, and the catalytic properties were related to the column density of pillared soapstone.
