摘　　要：以H_3PO_4、水铝石和硅溶胶为原料,四甲基氢氧化铵(TMAOH)为模板剂,在HF参与下水热晶化出含磷P型沸石和SAPO-20分子筛,得到2种分子筛的生成相区,并用^(31)P和^(29)Si MASNMR方法研究了杂原子的取代方式。The zeolite P containing phosphorus and SAPO-20 molecular sieve were synthesized by hydrothermal crystallization with H3PO4, boehmite and colloidal silica in the presence of HF and TMAOH as the template. The crystallization fields of the two molecular sieves were obtained by changing the contents of P, Al and Si in the reactants. The ways of heteroatom substitution were investigated by 31P and 29Si MAS NMR technique.
