水热法合成及培养出一种新型大单晶层状磷酸铝分子筛,AlPO_4-CJ.经多晶 X 射线衍射,四圆单晶 X 射线结构测定,其骨架 P 与 Al 原子比等于2,骨架 P 原子上有两个端基氧.三维空间包含质子化的乙二胺分子,乙二胺靠氢键支撑三维骨架.红外光谱表明骨架结构由 TO_4(T=P 或 Al)四面体构成.并研究其热稳定性能. Hydrothermal synthesis and culture of a new single crystal layered aluminum phosphate molecular sieve, AlPO 4-CJ by polycrystalline X-ray diffraction, tetragonal single crystal X-ray structure determination, the framework of P and Al atomic ratio equal to 2, the framework There are two terminal oxygen atoms on the P atom, the protonated ethylenediamine molecule is contained in the three-dimensional space, and ethylenediamine supports the three-dimensional framework by hydrogen bonds. The infrared spectrum shows that the framework structure is composed of TO_4 (T = P or Al) tetrahedra and Study its thermal stability.
