氧化铝、氧化镓交联粘土对1，2，4－三甲苯歧化反应催化性能的研究

Studies on the Catalytic Properties of 1, 2,4-Trimethtbenzene Disproportoonation Reaction over the Cross-Linking Clay with Al_2O_3 and Ga_2O_3

用多羟基铝及多羟基镓低聚物对合成皂石及临安土（浙江临安产的粘土）交联，制得氧化铝、氧化镓交联粘土，并表征了样品的物化性能，考察了样品对１，２，４－三甲苯歧化反应的催化性能。结果表明：交联粘土对１，２，４－三甲苯的歧化选择性较高（与Ｈβ沸石比较），且氧化镓交联粘土的异构选择性高于氧化铝交联粘土，氧化铝交联粘土的歧化选择性高（与氧化镓交联粘土及Ｈβ沸石比较）。

The cross-linking clay with Al2O3 and Ga2O3 were synthesized. The saponite and LinAn-clay cross-link with hydroxyl aluminium oligomer and hydroxyl gallium digomer and the samples were charadrized. The catalytic properties of 1,2,4-trimethybenzens disproportionation reaction with the samples were carried out.The results show that selectivity of disproportionation of 1,2,4-trimethybenzene was bigger with cross-linking day. The selectivity of isomerization with Ga2O3 cross-linking clay was bigger. The selectivity of disproportionation with Al2O3 cross-linking day was bigger.
