- 390 - MOLECULAR SIEVE COMPOSITIONS ABSTRACT Crystalline molecular sieves having three-dimensional microporous framework structures of ELO2, AlO2, SiO2 and PO2 framework oxide units are disclosed. The molecular sieves have an empirical chemical composition on an anhydrous basis expressed by the formula: mR : (ELwAlxPySiz)O2 wherein "R" represents at least one organic templating agent present in ths intracrystalline pore system; "m" represents the molar amount of present per mole of (ELwAlxPySiz)O2: "EL" represents at least one element capable of forming a framework oxide unit: and "w", "x". "y" and "z" represent the mole fractions of element(s) "EL", aluminum, phosphorus and silicon, respectively, present as framework oxides. Their use as adsorbents, catalysts, etc. is also disclosed.
