- 80 - MOLECULAR SIEVE COMPOSITIONS ABSTRACT Crystalline molecular sieves having three- dimensional microporous framework structure 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 molar amount of "R" present per mole of (MxAlyPz)O2; "M" represents at least one element capable of forming framework tetrahedral oxides and selected from the group consisting of arsenic, beryllium, boron, chromium, gallium, germanium, lithium and vanadium; 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.
