Abstract: Crystalline metal silicate compositions are prepared from a silica containing mixture which is substantially free of aluminum ions and which contains a chelating agent by digesting a reaction mixture comprising, a tetraalkylammonium compound, sodium hydroxide, a metal compound, an oxide of silicon, a chelating agent and water, with the reaction mixture containing less than about 100 ppm aluminum. Crystalline borosilicate compositions are of special interest. A method for activating the new crystalline compositions to enhance their usefulness for certain conversion processes is also disclosed.

Abstract: Transition metal carbonyl clusters intercalated with lamellar material such as graphite or smectites are prepared by reacting an intercalate of a transition metal halide with carbon monoxide at elevated temperature and at ambient to superatmospheric pressure. The intercalated complexes are useful in the catalysis of a variety of organic reactions including the water gas shift reaction, hydrogenation, hydroformylation, methanation, and so forth.

Abstract: New crystalline silicate compositions are prepared from a silica containing mixture which is substantially free of aluminum ions and contains a source of choline by digesting a reaction mixture comprising a choline salt, sodium hydroxide, potassium hydroxide, an oxide of silicon, water and, optionally, a Group VIII metal salt with the reaction mixture containing less than about 1000 ppm aluminum. These crystalline silicates exhibit a distinctive X-ray diffraction pattern and have a composition as expressed in terms of its oxides, as follows: ##EQU1## where R is the organic nitrogen-containing cation derived from choline, M is an alkali metal ion, ammonium, hydrogen, a metal cation or mixtures thereof, m is the valence of M, Z is a Group VIII metal cation and z is the valence of said Group VIII metal cation. These crystalline silicates are usefully employed as catalysts in hydrocarbon conversions.
