The method of producing oxygen 8-ring zeolite and aei-type zeolite

Without the use of quaternary ammonium salts of the expensive cyclic organic structure directing agent, inexpensive, with easy organic structure directing agent commercially available, efficiently producing oxygen 8-ring zeolite at a low cost. Aluminum atom raw material, a silicon atom raw material, an alkali metal atom raw material, an organic structure directing agent, and water were mixed, in a method of the obtained raw material mixture was hydrothermal synthesis to produce an oxygen 8-ring zeolite, as an aluminum atom material at least, it includes d6r the IZA is defined as composite building Unit in the skeleton, and Framework density is used 15T / 1000A3 following aluminosilicate zeolite, as the silicon atom raw material, at least, the aluminosilicate zeolite and, other than the silicon atom using a raw material, as organic structure-directing agent, at least, use of quaternary ammonium salts of 5 to 11 pieces have a carbon atom in the molecule.
