Abstract

Abstract: SAPO-11 Silicoaluminophosphate molecular sieves were synthesized in a hydrothermal system with an organic agent(di-n- or iso-propylamine). There are three method: (1)The aluminum source is aluminum isopropoxide. (2)An aluminophosphate solution was used in the reactive mixture. (3) The reactive mixture includes the fluo-anions. The framework structure and pore structure of SAPO-11 were studied by means of 2nd derivative IR, XRDand sorption in a vacuum. The conditions of synthesis of SAPO-11 were discussed.

Key words: Silicoaluminophosphate, Molecular sieve, Framework structure
