摘要： 新型AlPO4分子筛CFAP-5和硅磷铝分子筛CFSAPO-5分别水热合成于Pr3N(三丙胺)-Al2O3-P2O5-H2O体系和Pr2N-Al2O3-P2O5-SiO2-H2O体系中。反应物摩尔配比分别.为:Pr3N:Al2O3:P2O5:H2O=1:(1～1.2):1:(40～80)和Pr3N:Al2O3:P2O5:SiO2:H2O=1:(1～1.2):1:(0.5～2):(40～80),反应温度140℃。二丙胺亦可作为模板剂。经XRD、IR、TG、DTA和吸附等研究证明,CFAP-5在300～450℃之间、CFSAPO-5在300～600℃之间经焙烧后生成的相应分子筛,最大吸附孔径为4.4～4.9Å。

Abstract: A novel type of A1PO4 molecular sieves named CFAP-5 and silicophosphoalu-minate molecular sieves named CFSAPO-5 were synthesised hydro thermally in the system of Pr32O3-P2O5-H2Oand Pr3N-Al2O3-P2O5-SiO2-H2Orespectively. The molar composition of reactants is. Pr3N:Al2O3:P2O5:H2O = 1:(1~1.2):1:(40-80) for CFAP-5 and Pr3N:Al2O3 :P2O5:SiO2:H2O =1:(1~1.2): 1: (0.5-2): (40-80) for CFSAPO-5. Dipropylamine can also be used as "template". According to the study of XRD, 1R, TG, DTAand adsorption, the original product of CFAP-5 was changed into a form of molecular sieve after cal-cined at a range of 300-450℃ and CFSAPO-5 at a range of 300-600℃ respectively. The largest free dimension of adsorption window is 4.4-4.9A.
