摘要
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.
We have synthesized hydrothermally a novel layer aluminophosphate moleoularsieve,and obtained large single crystals.We prove that AIPO_4-CJ has layer-structure,the molar ratio of P/Al of the framework is equal to 2,and the P atom ofthe framework has two terminal oxygens by X-ray powder diffraction and four-circleX-ray diffraction.Three-dimensional space includes protonated ethylenediaminemolecules which sustain the framework of AIPO_4-CJ by forming hydrogen bond.Wealso measure it's infrared spectrum and study it's thermal stability.
