| 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. |
