ABSTRACT:
An aluminosilicate characterized by having a faujasite structure, a silica to alumina mole ratio of at least six and bis-(2-hydroxyethyl)-dimethylammonium ions or other large tetra alkyl or hydroxy alkyl ammonium ions within the large cages of the aluminosilicate. This composition may be prepared by crystallization from an aged reaction mixture to an oxide of sodium, a tetra alkyl or hydroxy alkyl ammonium salt, water, a source of silica, a source of alumina and sodium aluminosilicate nucleating seeds in specified relative amounts.
