N2 - A family of unusual lamellar aluminophosphates designated APO-Ln (L stands for lamellar and n=6, 8, 10, 12, the number of carbon atoms for the occluded template molecules) were synthesized from mixtures of phosphoric acid, aluminum triisopropoxide, ethylene glycol, an unbranched alcohol and a long-chain primary amine. The compounds were characterized by X-ray powder diffraction, scanning electron microscopy, magic angle spinning nuclear magnetic resonance spectroscopy, differential thermal analysis and thermogravimetric analysis. APO-Ln are composed of PO4, AlO4 and AlO6 structural units, and the ratio of the octahedral Al to the tetrahedral Al in the as-synthesized compounds is about 1:1. The APO-Ln exhibit a large weight loss when treated at elevated temperatures, and upon dehydration they adsorb a considerable amount of water. The water adsorption isotherms are linear, being different from the five conventional types of physical adsorption isotherms.
