Abstract:
1. A crystalline layered composition having an empirical composition in the as-synthesized form and on an anhydrous basis expressed by an empirical formula of: where M is at least one exchangeable cation selected from the group consisting of alkali metals, alkaline earth metals, and mixtures thereof, “m” is the mole ratio of M to Si and varies from about 0.01 to about 0.35, R is an organic cation selected from the group consisting of protonated amines, protonated diamines, quaternary ammonium ions, diquaternary ammonium ions, protonated alkanolamines and quaternized alkanolammonium ions, “r” is the mole ratio of R to Si and varies from about 0.05 to about 1.0, “n” is the weighted average valence of M and varies between about 1 and about 2, “p” is the weighted average valence of R varies from 1 to about 2, H is a hydroxyl proton and “w” is the mole ratio of H to Si and varies from 0 to about 1.0, “x” is the mole ratio of Al to Si and varies from greater than 0 to about 0.25, E is an element which is tetrahedrally coordinated, is present in the framework and is selected from the group consisting of gallium, iron, chromium, indium, boron and mixtures thereof, and “y” is the mole ratio of E to Si and varies from 0 to about 0.25, and x+y is greater than 0.01 to about 0.25, “z” is the mole ratio of O to Si and is given by the equation: the layered composition characterized in that it has an x-ray diffraction pattern having at least the d-spacings and relative intensities set forth in one of Tables A, B or C .
