Formation of Intermediate Phases during Crystallization of Aluminophosphate and Silicoaluminophosphate Sieves with the AEL Structure

Agliullin, M. R. / Kuvatova, R. Z. / Kutepov, B. I.

Using X-ray powder diffraction analysis, ²⁷Al and ³¹P magic angle spinning nuclear magnetic resonance, and nitrogen adsorption–desorption, it has been shown that, during the crystallization of AlPO₄-11 and SAPO-11 molecular sieves, the use of pseudoboehmite as an aluminum source leads to the formation of intermediate phases, which are crystalline aluminophosphates AlPO₄ · 2H₂O and isostructural silicoaluminophosphates with a mesoporous structure.
