摘要
本文探讨了金属离子同晶取代〔Al_(13)〕^(7+)中部分铝离子,制得二元金属羟基低聚物,并与临安土交联,结果发现,铁、镓、铬等金属离子能同晶取代〔Al_(13)〕^(7+)中的Al^(3+)而形成二元金属羟基低聚物,且这些羟基低聚物与临安上交联产物的结晶度和热稳定性较好,在异丙苯裂解反应中有丙烯二聚的能力。
It was studied that the isomorphous substitution took place with the metal ions replacing some of Al ions of [Al13]7+, and the hydroxymers involving two kinds of metals were synthesized and crosslinked with Linan clay. The results indicate that the isomorphous substitution took place with Fe,Ga,Cr tons etc. replacing Al3+ ions of [Al13]7+, and the samples cry stallinity was better. The samples were sysnthesis by the hydroxymers pillaring LinAn clays. They had abilities making the propene dimerize in the cracking of cumene.
