摘　　要：采用超增溶自组装法合成纳米级AlPO1-5分子筛,考察了焙烧温度、乳化剂质量分数对分子筛粒径及其分布的影响，结果表明在超增溶纳米自组装的条件下能够合成出类球形的纳米磷铝分子筛，并且通过调节乳化剂的质量分数可以控制纳米分子筛的粒径大小，纳米磷铝分子筛直径为10～80nm，长度为0．1～0．2μm。Used the method of super solubility and self-assembly to synthesize AlPO1-5 nanoparticle zeolites. Studied the impacts on molecular sieves from different calcination temperatures and the volume of emulsifier to change the particle sizes and the distribution, and the results showed that this method can synthesize phosphorus and aluminum molecular sieves. Meanwhile, the way of adjusting the volume of emulsifier to change the particle sizes and the distributiosn can synthesize nano AlPO1- 5 molecular sieves,its particle sizes is 10~80 nm,and the length is 0. 1-0.2μm.
