本专利介绍一类新颖的微孔结晶分子筛及其制备方法。这种分子筛具有MO_2、AlO_2、PO_2四面体氧化物单元的三锥微孔骨架结构。由实验测出无水形式的该分子筛的化学组成可由下列分子式表示:mR:(M_xAl_yP_z)O_2,此处R代表一种或一种以上的有机成膜
This patent describes a new class of microporous crystalline molecular sieve and its preparation method. The molecular sieve has a trilobal microporous framework structure of MO 2, AlO 2 and PO 2 tetrahedral oxide units. The chemical composition of the molecular sieve in anhydrous form as determined experimentally can be represented by the following formula: mR: (M_xAl_yP_z) O_2 where R represents one or more organic film-forming
