ABSTRACT:
This invention relates to a method for preparing a synthetic porous crystalline aluminosilicate zeolite, characterized as zeolite ZSM-45. This crystalline material may have a silica to alumina molar ratio of at least 8. This synthetic zeolite is analogous, in some respects, to the naturally occurring zeolite, levynite. The ZSM-45 zeolite is prepared with a dimethyldiethylammonium directing agent. ZSM-45 exhibits a characteristic X-ray diffraction pattern.
