Abstract: The aluminophosphate molecular sieve VPI-5 has been received much attention as a new structure containing super-large open pores with 18 tetrahedral atoms.During the propcess of dehydration and desorption of water molecules in the channeles, the framework structure can be converted into AlPO4-8, which contains 14-membered ring open pores.The process of phase transformation was studied and the mechanism about the transformation is discussed.
Key words: VPI-5, AlPO4-8, Aluminophosphate molecular sieve
