摘要: 以二正丙胺及二异丙胺为模板剂,采用水热法制得了SAPO-11分子筛,对3种不同的合成方法——异丙醇铝法、上清液法和氟离子法的产物及杂晶情况作了讨论,采用红外和二次微分红外光谱、XRD多晶结构分析及真空吸附等方法研究了SAPO-11的骨架结构和孔结构。

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
