EFFECT OF pKa VALUE UPON INTERCALATION OF HETEROCYCLIC COMPOUND INTO LAYERED PHOSPHATE

Abstract

The arrangement of heterocyclic compound in the intercalation compounds of the α- and γ-type zirconium and titanium phosphates, and the effect of pKa values of guest compounds on the intercalation into layered phosphates, were examined. An appreciable difference in the arrangements of aminopyridines between α- and γ-types was not found. The intercalation of heterocyclic compounds into layered phosphates depended on their pKa values. In the intercalation of heterocyclic compounds, α-type layered phosphate was more strongly influenced by the pKa values of the guest compound than that of γ-type.
