Delamination and intercalation of layered aluminophosphate with [Al3P4O16](3-) stoichiometry in water/alcohol/amine solutions
Delamination and intercalation of a layered microporous aluminophosphate [Al3P4O16](3-).3[CH3CH2NH3](+) (AlP) were carried out in water/ethanol/amine and water/methanol/amine solutions. A good colloidal dispersion and saturated amine intercalates of the aluminophosphate can be obtained in solutions with dielectric constants in the range 50-70 and an amine concentration of 10 mmol/g AlP. The saturated C-2-C-12 amine intercalates of All? with an even number of carbon atoms are packed with alkylamine bilayers tilted at an angle of 44.8degrees in the interlayer region.
