| Aspects of the present invention relate to an improved process for exchanging alkali metal or alkaline earth metal ions in zeolites for ammonium ions. For this exchange, aqueous solutions of ammonium salts, for example ammonium sulfate, ammonium nitrate or ammonium chloride, are currently being used. The resulting “ammonium zeolites” are calcined to convert them, with release of ammonia, to the H form of the zeolites suitable as a catalyst. Certain methods provided herein use ammonium carbonate instead of the ammonium compounds mentioned. As excess ammonium carbonate, in contrast to the nitrates, sulfates or chlorides, can be recycled in the form of carbon dioxide and ammonia, the amount of salt which has to be discharged is lowered significantly. | ||||||

| The present invention is directed to open-framework and microporous solids particularly well suited for use in catalysis and ion exchange. The microporous solids are constructed by using a salt template which can be readily removed without destroying the framework of the micropore. Various microporous solids can be formed having different geometric structures depending upon the templating salt used and the concentration. Examples of two compounds include Na2Cs[Mn3(P2O7)2]Cl(1) and K2.02Cs2.90[Cu3(P2O7)2]C12.92(2). Compound 1 crystallizes in the space group C2/c with a=21.210(8), b=5.272(2), c=13.924(2)Å, beta=119.04(2), and Z=4. Compound 2 crystallizes in the space group 14/mcm with a=b=18.001(3), c=13.530(4)Å, and Z=8. Both compounds have 3-D (Mn, Cu)-P-O frameworks. For 1, two MnO4, two MnO5 polyhedra and four PO4 tetrahedra form small tunnels where Cs+ and Cl− ions reside. For 2, CuO4 and P2O7 groups form two different tunnels, one is similar to that in 1 (ca. 5.3 Å in diameter) while the other formed by eight CuO4 polyhedra and eight PO4 tetrahedra has an approximate diameter of 12 Å. | ||||||
