ABSTRACT:
A process for producing a crystalline aluminosilicate which 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, characterized in that said starting mixture comprises at least two colloids having different silicon/aluminum atomic ratios, and that the hydrothermal reaction is carried out, as required, in the presence of a fluorine compound.
