Molecular sieve compositions having three-dimensional microporous framework structures of BO.sub.2, AlO.sub.2, PO.sub.2 and SiO.sub.2 tetrahedral oxide units are disclosed. These molecular sieves have an empirical chemical composition on an anhydrous basis expressed by the formula: mR:(B.sub.w Al.sub.x P.sub.y Si.sub.z)O.sub.2 wherein "R" represents at least one organic templating agent present in the intracrystalline port system; "m" represents the molar amount of "R" present per mole of (B.sub.w Al.sub.x P.sub.y Si.sub.z)O.sub.2 ; and "w", "x", "y" and "z" represent the mole fraction of boron, aluminum, phosphorus and silicon, respectively, present as tetrahedral oxides. Their use as adsorbents, catalysts, etc. is also disclosed.
Crystalline molecular sieves comprising three-dimensional microporous framework structures of BO.sub.2, AlO.sub.2, PO.sub.2 and SiO.sub.2 tetrahedral units having an empirical chemical composition on an anhydrous basis expressed by the formula:
Process for preparing crystalline molecular sieves having three-dimensional microporous framework structures of BO.sub.2, AlO.sub.2, PO.sub.2 and SiO.sub.2 tetrahedral units having an empirical chemical composition on an anhydrous basis expressed by the formula:
Molecular sieve prepared by calcining, at a temperature sufficiently high to remove at least some of any organic templating agent present in the intracrystalline pore system, a crystalline molecular sieve having three-dimensional microporous framework structures of BO.sub.2, AlO.sub.2, PO.sub.2 and SiO.sub.2 tetrahedral units having an empirical chemical composition on an anhydrous basis expressed by the formula:
