INTERCALATION OF ORGANIC MOLELECULES INTO LAYERED PHOSPHATES

Precise investigation of intercalation compounds of layered phosphates by solid state NMR could explore the microscopic picture of intercalation phenomena. By 31P solid state NMR experiment, type of layered phosphate and existence of various phosphates, H2PO4-, HPO42-, and PO43- groups, can be distinguished. The microscopic picture of diethylenetriamine-intercalated α-zirconium phosphate, and its mechanism can be obtained by 13C and 31P solid state NMR. Furthermore, the adsorption of carboxylic acids by diethylenetriamine-intercalated α-zirconium phosphate and the exchange of methylene blue with butylamine in butylamine-intercalated α-zirconium phosphate can be clarified microscopically.
