EXPERIMENTAL STUDY ON INTERCALATION OF ORGANIC COMPOUNDS INTO KAOLINITE STRUCTURE

Zhong Yuan Chen Kaihui(Institute of Geology, Academia Sinica, Beijing)  
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℃.
