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.
