A KAOLINITE-NMF-METHANOL INTERCALATION COMPOUND AS A VERSATILE INTERMEDIATE FOR FURTHER INTERCALATION REACTION OF KAOLINITE

A kaolinite-organic intercalation compound containing methanol was pro ved to be a versatile host for further displacement reaction with aIky lamines, Kaolinite-organic intercalation compounds with polar molecule s, such as N-methylformamide (NMF) and formamide, were used as the sta rting materials. After stirring the kaolinite-NMF intercalation compou nd with methanol, the basal spacing increased to 1.11 nm. The C-13 MBS NMR result of the product indicated that methanol was intercalated in to kaolinite by partial displacement with NMF. By use of the methanol- treated kaolinite intercalation compound as the intermediate, alkylami nes were intercalated into the interlayer space of kaolinite by displa cing with methanol.
