摘要/Abstract

摘要： 新AlPO₄结晶分子筛相CFAP-2合成于TMEDA(N,N,N′,N′-四甲基乙基二胺)-P₂O₅-A1₂O₅-H₂O系统,反应物摩尔组成的范围是:TMEDA:P₂O₅:Al₂O₃:H₂O=(1—1.1):1:1:50,晶体形貌,X射线粉末衍射分析,热分析及红外光谱的研究表明:CFAP-2与A1PO₄-21的晶体结构不同,在350℃时,CFAP-2的原粉相转变为具有三维骨架孔结构的较稳定的结晶相。

Abstract: Anovel type of A1PO₄ molecular sieves named CFAP-2 was synthesized hydrothermally in a TMEDA (tctramethylethylenediaminc)-P₂O₅-Al₂O₃-H₂Osystem at 200℃.The mole ratio composition of reactant was TMEDA:P₂O₅ :Al₂O₃ :H₂O=(1 - 1.1) : 1:1: 50. Studies of crystal morphology, X-ray powder diffraction analysis, thermoanalysis and infrared spcctroscopy lead to the conclusion that CFAP -2 is different from AlPO₄-21 in crystal structure. Transformation of the original product into more stable crystal phase with porous 3-dimensional framework occured at 350℃. The free dimension of the adsorption window of CFAP-2' is between4.4-4.9Å.
