Abstract
Abstract A process for producing a crystalline aluminosilicate comprises hydrothermally reacting a starting mixture composed of a silicon compound, an aluminum compound, an alkali metal compound, a compound capable of releasing an organic cation in water and water, the starting mixture comprising at least two colloids having different silicon/aluminum atomic ratios, and the hydrothermal reaction optionally being carried out in the presence of a fluorine compound.
