14 synthetic crystalline aluminosilicate is prepared by an inorganic process from a reaction mixture, which contains in an aqueous alkaline medium SiO2 and A1 2O3 or their hydrated derivatives or alkali silicates and, aluminates, mineralizers and optionally seeding crystals, the reaction mixture containing SiO2/A12O3 in molar ratio of 15 - 40, OH-/siO2 in molar radio 0.1 - 0,2, and H20/Si02 in molar ratio 20 - 60. The aluminosilicate produced by the process has a chemical composition expressed in molar ratios as: 0-3 M20 : Al203 : 15 - 40 Si0 2 : 0 - 40 H2O, where M represents an alkali cation. The aluminosilicate is useful in the preparation of catalysts and adsorbents.
