摘　　要：以Silicate-1晶种为硅源,水热合成了一种新型介孔磷酸硅铝(SAPO-1)分子筛,并且通过X射线粉末衍射、红外光谱、透射电镜、扫描电镜、热重分析、N2吸附/脱附和氨气程序升温脱附(NH3-TPD)等多种手段对产物进行了表征.红外光谱表明,Silicate-1导向剂成功地引入了介孔骨架;氨气程序升温脱附(NH3-TPD)结果表明,SAPO-1具有较强的酸性.催化结果表明,SAPO-1在大分子催化反应中有较高的活性.A new type of mesoporous silicoaluminophosphate （SAPO-1） with worm-like structure was synthesized by hydrothermal method with embryonic silicate zeolite as the Si source. The slicoaluminophosphate molecular sieve was characterized by XRD, IR, TEM, SEM, TG and N2 adsorption/desorption techniques. The results showed that SAPO-1 had a stronger acidity than the empirical SAPO prepared from TEOS. The catalytic reaction results showed that SAPO-1 was more active than conventional SAPO-2.
