摘要：

Metal phosphates have been widely used as catalysts in many organic reactions for their acid-base and redox properties[1,2]. Their structure and properties are affected greatly by the preparation method[2-5]. AlPO4 is one of the most important metal phosphates. There are many different phases of AlPO4) that is, amorphous, crystalline and molecular sieve. The usual methods of preparation of AlPO4 are described elsewhere[1,3], i.e. gelification of a mixture of an aluminum salt (chloride, nitrate etc.) with orthophosphoric acid (or NaH2PO4) in the presence of a base. Ammonia, ethylene oxide, and propylene oxide are used as base mostly.
