Abstract
Abstract Crystalline molecular sieves having three-dimensional microporous framework structures of MnO<sub>2</sub>, AlO<sub>2</sub>, SiO<sub>z</sub> and PO<sub>2</sub> tetrahedral oxide units are disclosed. These molecular sieves have an empirical chemical composition on an anhydrous basis expressed by the formula: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 (Mn<sub>w</sub>AI<sub>x</sub>P<sub>y</sub>Si<sub>z</sub>)O<sub>2</sub>; and"w", "x", "y" and "z" represent the mole fractions of manganese, aluminum, phosphorous and silicon, respectively, present as tetrahedral oxides. Their use as adsorbents, catalysts, etc. is also disclosed.
