【摘要】 用水热合成法合成ＳＡＰＯ－５分子筛。采用廉价的三乙胺（Ｆｔ＿３Ｎ）、正三丙胺（ｎ－Ｐｒ＿３Ｎ）代替四乙基氢氧化胺（ＴＥＡＯＨ）￣［１］作为有机导向剂，以降低合成费用。考察了不同的胺／Ａｌ比、Ｐ／Ａｌ比、Ｓｉ／Ａｌ比以及Ｈ＿２／Ａｌ比对结晶相的影响，从而得出合成ＳＡＰＯ－５分子筛的适宜配比，并且给出了不同温度下产物结晶度随时间变化的晶化曲线。用程序升温法（ＴＰＤ）表征了ｓＡＰＯ－５分子筛（Ｈ型）的酸性分布。另外还考察了用Ｅｔ＿３Ｎ、ｎ－Ｐｒ＿３Ｎ、ＴＥＡＯＨ三种不同导向剂制备的三个ＳＡＰＯ－５样品的热稳定性和吸附性能。更多还原

【Abstract】 SAPO-5 zeolite was obtained by hydrothermal synthesis.To decrease the cost of synthesis,we used Et₃N,n-pr₃N as organic templates instead of TEAOH. The influence of differentamine/Al ratio, P/Al ratio,Si /Al ratio and H₂O/Al ratio in the reactive mixture on thecrystallization phase Was investigated,and the proper reactive ratio of synthesis SAPO-5zeolite was given. In addition,We have shown the crystallization curve of product at differenttemperatures.The acidic distribution of sample was characterized by temperature-programmed desorp-tion（TPD）.Also,the thermal stability and adsorptivity of three SAPO-5 samples,whichwere prepared by three templates（Et₃N,n-pr₃N and TEAOH）,were examined.更多还原
