摘要
进行了Mo6+、W6+等高价离子引入T-O-T层的尝试,发现在合成皂石的条件下它们不能引入T-O-T层.而Si、Mg可形成T-O-T层.用[Al13]7+交联Si-MgT-O-T层得交联粘土,对其表征发现、铝交联Si-MgT-O-T层的总酸量小(与合成皂石相比),并且只有L酸中心无B酸中心.
Attempt to synthesis the T-O-T layer containing Mo 6+ and W 6+ ions has been done.The results show that Mo 6+ and W 6+ could not be intercalated into T-O-T layer,but Si and Mg T-O-T layer could been prepared.Cross-linking clay was prepared with [Al 13 ] 7+ cross-linking Si-Mg T-O-T layer,and was charaterized.The results indicated that the acidamount of aluminium cross-linking Si-Mg T-O-T layer has less acidily than that of the synthesized saponite,and the aluminum cross-linking Si-Mg T-O-T layer had only Lewis acidsites,but not Bronsted acid sites.
