摘要： 在Al2O3-P2O5-六次甲基四胺-H2O体系中,水热合成出新型磷酸铝分子筛(AlPO4-CJ2),培养了单晶,经多晶X射线衍射、四圆单晶结构测定及红外光谱研究证明,AlPO4-CJ2具有空旷的骨架结构,沿(100)和(001)方向具有8元环孔道,骨架中Al原子以AlO5(三角双锥)和AlO5F(扭曲八面体)形式存在,水分子氧的桥联产生Al-O-Al连接模式。

Abstract: Anovel aluminophosphate molecular sieve (A1PO4-CJ2) was synthesized hydrothermally from the system of Al2O3-P2O5-hexamethylenetetramine-H2O, and a large single crystal was obtained. It was proved that AIPO4-CJ2hasan open framework, and has 8-Tring channels along the direction (100) and (001) respectively determined by X-ray diffraction, four-circle X-ray diffraction and IRspectrum and that the Al atoms of the framework are located in AlO5(distorted trigonal bipyramid) and AlO5F (distorted octahedron). A model of Al-O-Al linkage is formed by bridge of the oxygen atom of water molecules.
