Sayari et al. [209-212] followed another path to the synthesis of mesolamellar aluminophosphates. They used AI2O3, H3PO4 and primary or tertiary amines as surfactants in aqueous media. The surfactant was found to be protonated while acting as template. Effects of synthesis parameters such as Al/P, P/amine, P/H2O ratios were studied systemically by XRD and Al and P NMR. The connectivity between Al and P was found to be dependent on the synthesis parameters.
