含Mo^(6+)、W^(6+)T-O-T层合成的探索与Si-MgT-O-T层的合成和表征

ATTEMPT TO SYNTHESIS THE T-O-T LAYER CONTAINING Mo 6+ AND W 6+ IONS,AND THE SYNTHESIS AND CHARACTERIZATION OF Si-Mg T-O-T LAYER

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.
