【摘要】 用水热法合成了磷酸镁铝分子筛(MAPO-5),以X射线衍射、电子探针、核磁共振及红外光谱等方法进行了结构分析,并测定了MAPO-5分子筛的晶胞参数、化学组成,同时对分子筛的吸附性能、热稳定性、酸性等进行了研究。证明镁进入了分子筛的骨架。更多还原

【Abstract】 Magnesium aluminophosphate (MAPO-5) molecular sieve was synthesized by hydrothermal method. The crystal structure of MAPO-5 has been studied by X-ray diffraction, electron probe, 31P-Nuclear Magnelic Resonance and infrared spectra. The parameters of the unite cell and chemical composition of MAPO-5 have been determined. Some physicochemical properties of MAPO-5 such as adsorption capacity, thermal stability and acid have been investigated. These results illustrates that Magnesium enter the framework of MAPO-5 molecular sieve.更多还原
