Title:

ZSM-48 HAVING NOVEL CRYSTAL MORPHOLOGY

Document Type and Number:

Japanese Patent JP2011042574

Kind Code:

A

Abstract:

To provide a ZSM-48 product which reduces manufacturing expense and is more excellent.

A method for preparing ZSM-48 comprises: (a) preparing a reaction mixture comprising a source of silica (silicon dioxide), a source of trivalent metal oxide, an alkali metal oxide and a directing agent of ethylenediamine in a solvent phase comprising water, wherein the mixture, in terms of mole ratios of oxides, has the following composition ranges: SiO2/Me2O3: 100 to 1,500, M/SiO2: 0 to 0.4, RN/SiO2: 1.0 to 5.0, OH-/SiO2: 0 to 0.3, and H2O/SiO2: 10 to 100, wherein Me is trivalent metal, M is alkali metal and RN is ethylenediamine; and (b) the mixture is maintained under crystallization conditions until crystals of ZSM-48 are formed.
