分别在NH_4OH和NaOH介质中用羟基铝低聚物交联临安土和累托石。结果表明,二种介质中均能制得交联产物,且NH_4OH介质中交联物的表面酸性、异丙苯裂解活性均高于NaOH介质中的交联产物。从而体现了NH_4OH介质中交联的优越性。
Lin’an earth and rectorite were crosslinked with hydroxy aluminum oligomers in NH4OH and NaOH media, respectively. The results showed that the crosslinked products were obtained in both media, and the surface acidity and the cumene cleavage activity of the crosslinked products in NH 4 OH medium were higher than those in NaOH medium. Thus reflecting the superiority of crosslinking in NH 4 OH medium.
