氧化铝、氧化镓交联黏土的合成、表征及催化活性

Synthesis, Characterization & Catalytic Activity of Cross-linked Clay with Al_2O_3 & Ga_2O_3

以多羟基铝及多羟基镓低聚物为交联剂与合成皂石及临安土(浙江临安产精制钠基膨润土)交联,制得氧化铝氧化镓交联黏土催化剂,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:交联黏土催化剂对1,2,4-三甲苯歧化反应具有较好的催化活性。

The cross-linked clays with Al2O3 and Ga2O3 were synthesized by the prepared saponite and Linan-clay with hydroxy aluminium oligomer and hydroxy gallium oligomer . The samples were characterized. The catalytic properties of 1,2, 4-trimethylbenzens disproportionation reaction with the samples were carried out. The results showed that the cross-linked clay had better catalytic activity to the disproportionation of 1, 2, 4- trimethylbenzene.
