| 摘 要： | 磷酸铝分子筛是新的一类晶态无机材料.1982年美国联合碳化物公司首次公布了约廿种不同结构的磷酸铝分子筛的合成专利[1],作者在研究P2O5-Al2O3-H2O系统的水热合成中[2],发现用Al2(SO4)3溶液作为Al2O3源,固体(NH4)3PO4·3H2O作为P2O5源,加入适量的有机胺,也能合成分子筛相,新晶态分子筛CFAP-6就是用上述原料,在二正丁胺-(NH4)2O-P2O5-Al2O3-H2O系统中水热合成的。

| Abstract: | A novel crystalline aluminophosphate CFAP-6 was synthesized hydro thermally in a system of di-n-butylamine-(NH4)2O-P2O5-Al2O3-H2O, the P2O5 and Al2O3 sources of which were (NH4)3PO4·3H2Oand Al2(SO4)3 aqueous solutionrespectively.The mole ratio composition of rcactant was: di-n-butylamine/(NH4)2O/P2O5/Al2O3/H2O = (1~1.2)/(3~3.6)/(l~1.2)/l/67.The reaction is conducted at 200℃. Investigations of DTA, XRD, IRand the adsorption experiment show that transformation of the raw powder (phase a) into more stable crystal form (phase b) with properties of molecular sieve, on heating at 350℃ and giving H2O and amine(or ampnia) off. Isotherms for the adsorption of H2O and CH3OH at 23℃ indicate that the dimension of the adsorption window of CFAP-6 is between 4.3 and 4.9Å and the. capacity about 0.07mL/g. |
