摘 要: | 以异丙醇铝、磷酸、正硅酸乙酯为反应原料,三乙胺作为模版剂,功率800 W、180℃微波辐射30min合成了粒径均一、具有AFI拓扑结构的SAPO-5分子筛,系统研究了Al2O3与SiO2摩尔比和HF添加量等因素对产物长径比和晶体形貌的影响。采用XRD、SEM等分析手段对产物进行表征。结果表明,n(Al2O3)/n(SiO2)可以控制晶体尺寸的大小以及长径比,HF的存在影响晶体的成核及分散性。

Synthesis and characterization of SAPO-5 molecular sieve by microwave irradiation |

Abstract: | SAPO-5 molecular sieve was compounded by microwave irradiation using Al(OPri)3, H3PO4,C8H20O4Si as the reaction material and triethylamine as a temple at 180℃for 30min.Some factors influencing on products such as n(Al2O3)/n(SiO2),HF dosage were systematically studied. The products were characterized by XRD,SEM and results showed that n(Al2O3)/n(SiO2)could control the crystal size and HF dosage could influence the nucleation and dispersion. |
