Abstract (en)
[origin: WO8901912A1] Crystalline aluminumphosphate compositions having three-dimensional microporous crystal framework structures whose chemical composition expressed in terms of mole ratios is Al2O3:1.0+/-0.2 P2O5 are disclosed. Adsorption data shows that the compositions are useful as molecular sieves, having intracrystalline micropores capable of admitting molecules having kinetic diameters of from 3 to 14 Angstroms. These compositions have an X-ray diffraction pattern characterized by d spacings at less than about 40 degrees two-theta as measured using copper K-alpha radiation that are substantially as shown in Table 1. The compositions can further comprise a structure-directing agent. Preparation is by admixing an aluminum source, a phosphorus source and 10-100 moles of water per mole of Al2O3 to form a precursor mixture, admixing the precursor mixture with the structure-directing agent to form a reaction mixture, and reacting the reaction mixture under conditions such that an aluminumphosphate composition of the given X-ray diffraction pattern is formed. Metal substituted aluminumphosphate compositions having an X-ray pattern with the same characterizing d spacings can also be prepared such that oxides of one or more metals are also incorporated in the oxide lattice. Among the metals suitable for substitution are silicon, magnesium, zinc, tin, zirconium, titanium, cobalt, and mixtures thereof.
