Metallophosphate molecular sieves, method of preparation and use

A process for preparing a microporous crystalline metallophosphate having a three-dimensional framework of EO2−, PO2+ and at least one of [M2+O2]2− and SiO2 tetrahedral units and a composition in the as synthesized and anhydrous basis expressed by an empirical formula of:

• RrMm2+EPxSiyOz
• where M is at least one framework cation of valence 2+ selected from the group consisting of alkaline earth and transition metals, “m” is the mole ratio of M to E and varies from 0 to about 1.0, R is an organoammonium cation selected from the group consisting of ethyltrimethylammonium (ETMA+), diethyldimethylammonium (DEDMA+), and mixtures thereof, “r” is the mole ratio of R to E and has a value of about 0.1 to about 2.0, E is a trivalent element selected from the group consisting of aluminum, gallium, iron(III), boron and mixtures thereof, “x” is the mole ratio of P to E and varies from 0.5 to about 2.0, “y” is the mole ratio of Si to E and varies from 0 to about 1.0, “m”+“y”≧0.02, and “z” is the mole ratio of 0 to E and has a value determined by the equation:
• z=(2·m+r+3+5·x+4·y)/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 A1:

• the process comprising forming a reaction mixture containing reactive sources of R, E, P, at least one of M and Si, and heating the reaction mixture at a temperature of about 60° C. to about 200° C., for a time sufficient to form the metallophosphate, the reaction mixture having a composition expressed in terms of mole ratios of the oxides of:
• aR2O:bMO:E2O3:cP2O5:dSiO2:eH2O
• where “a” has a value of about 0.25 to about 16, “b” has a value of about 0 to about 2.0, “c” has a value of about 0.8 to about 8, “d” has a value of about 0 to about 4, and “e” has a value of about 30 to 800 and wherein the sum of the values of “b” and “d” is greater than 0.01.
