Intercalation of N, N-dimethyl-1-phenylethylamine into α-Zirconium Phosphate

The intercalation and deintercalation of N, N-dimethyl-1-phenylethylamine (N,N-amine) into α-zirconium phosphate was investigated by pH titration. N,N-amine was taken up easily in one step to give a new phaseZr(HPO4)(HPO4·N,N-amine) · H2O, which was characterized by X-ray diffractometry, IR spectroscopy, and thermal analysis. Therelease of N,N-amine from the solid was found to be irreversible due to structural changes in both the intercalation and deintercalation reactions.
