Abstract

In this work, the crystallization process for the open-framework aluminophosphate AlPO-HDA (Al₁₆P₂₀O₈₀H ₄·4C₆H₁₈N₂) has been studied in the hydrothermal system Al(i-PrO)₃-H₃PO ₄-1,6-hexanediamine-H₂O by XRD, ICP, ²⁷Al and ³¹P MAS NMR techniques. An intermediate phase Al₅P ₅O₂₀(OH)₂·C₆H ₁₈N₂·3H₂O, denoted APO-M1, with an Al/P ratio of 1:1 is formed firstly, then transformed to AlPO-HDA. The study on the crystallization of AlPO-HDA might give some insight into the formation mechanism of microporous materials.
