Aluminophosphate molecular sieves AlPO4-5 is a representative of phosphate molecular sieve,its excellent catalytic performance has been widely accepted. The compositions of the gel directly affect the composition and properties of the product. In this paper,the AlPO4-5 molecular sieve was synthesized by the hydrothermal method. With orthophosphoric acid(H3PO4)as P source,pseudo-boehmite as Al source and triethylamine(TEA)as template,it was obtained by crystallization 36 h under 180℃. Powder X-ray diffraction(XRD)patterns and electronic microscopy techniques were employed to characterize the AFI phase structure and morphology characterization of AlPO 4-5 respectively,we have investigated the effect of different amounts of water,templates and changing both at the same time to the synthesis AlPO4-5 respectively.
