Crystalline molecular sieves having three-dimensional microporous framework structures of MO2, AlO2, and PO2 tetrahedral oxide units are disclosed. These molecular sieves have an empirical chemical composition on an anhydrous basis expressed by the formula: mR : (MxAlyPz)O2 wherein "R" represents at least one organic templating agent present in the intracrystalline pore system; "m" represents the amount of "R" present per mole of (MxAlyPz)O2; "M" represents at least two elements capable of forming framework tetrahedral oxides, where "M" is at least one element selected from the group consisting of arsenic, beryllium, boron, chromium, iron, gallium, germanium, lithium and vanadium and at least one element selected from the group consisting of cobalt, iron, magnesium, manganese, titanium and zinc; and "x", "y" and "z" represent the mole fractions of "M", aluminum and phosphorus, respectively, present as tetrahedral oxides. Their use as adsorbents, catalysts, etc. is disclosed. |
