摘要
详细研究了某些有机化合物在高岭石层间的夹层作用及其稳定性。极性化合物水合联胺与高岭石的夹层作用,其最大层间膨胀值可达11.33 且较稳定。红外吸收光谱表明,极性有机物对层间的OH基有扰动作用。脂肪酸盐和丙烯酰胺可分别通过水合联胺及甲酰胺做夹带剂与高岭石进行夹层作用,作用结果,其层间距可分别从7 扩大到11 及11.05 ,前者在常温下比较稳定;后者在加热时是稳定的,但温度超过300℃,d_(001)值又恢复到7 。
Detailed study on intercalation of some organic componds in kaolinite and its stability is made in this paper. The c-axis spacing in kaolinite expands to a largest value 11.33A as a result of intercalation of polar compound hydrazine into kaolinite. The expansion value is relatively stable, and rather strong perturbation of the OH stretching on the intercalation is observed in IR spectra. The salts of fatty acids and acrylamide can intercalate into the kaolinite by virtue of cntrainer, the resulting intercalation compound shows a bassic spacing of 11A and 11.05A respectively. The former, is relative stable at normal emperature and the latter is stabile when heated but can be decompose when the temperature exceeds 300℃.
