Lithium-aluminum-phosphorus-oxide molecular sieve compositions

摘要

Molecular sieve compositions having three-dimensional microporous framework structures of LiO2, 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: (LixAlyPz)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 (LixAlyPz)O2; and "x", "y" and "z" represent the mole fractions of lithium, aluminum and phosphorus, respectively, present as tetrahedral oxides. Their use as adsorbents, catalysts, etc. is also disclosed.
