High charge density metallophosphate molecular sieves

A microporous crystalline metallophosphate material having a three-dimensional framework of [M2+O4/2]2−, [EO4/2]− and [PO4/2]+ and tetrahedral units and an empirical composition in the as synthesized form and on an anhydrous basis expressed by an empirical formula of:

• Rp+rA+mM2+xEyPOz
• where R is at least one quaternary ammonium cation selected from the group consisting of tetraethylammonium (TEA+), triethylpropylammonium (TEPA+), diethylmethylpropylammonium (DEMPA+), dimethylethylpropylammonium (DMEPA+), dimethyldipropylammonium (DMDPA+), methyltriethylammonium (MTEA+), ethyltrimethylammonium (ETMA+), diethyldimethylammonium (DEDMA+), choline, hexamethonium (HM2+), propyltrimethylammonium (PTMA+), butyltrimethylammonium (BTMA+), tetramethylammonium (TMA+), tetrapropylammonium (TPA+) and mixtures thereof, “r” is the mole ratio of R to P and has a value of about 0.04 to about 1.0, “p” is the weighted average valence of R and varies from 1 to 2, A is an alkali metal selected from the group consisting of Li+, Na+, K+, Rb+ and Cs+ and mixtures thereof, “m” is the mole ratio of A to P and varies from 0.1 to 1.0, M is a divalent element selected from the group of Zn, Mg, Co, Mn and mixtures thereof, “x” is the mole ratio of M to P and varies from 0.2 to about 0.9, E is a trivalent element selected from the group consisting of aluminum and gallium and mixtures thereof, “y” is the mole ratio of E to P and varies from 0.1 to about 0.8 and “z” is the mole ratio of 0 to P and has a value determined by the equation:
• z=(m+p·r+2·x+3·y+5)/2
• and is characterized in that it has the x-ray diffraction pattern having at least the d-spacings and intensities set forth in Table A:
