Abstract
This invention relates to a new synthetic porous zeolite, characterize as ZSM-45, a method for its preparation and use thereof in catalytic conversion of organic compounds. This crystalline material may have a ratio of XO.sub.2 :Y.sub.2 O.sub.3 of at least 8, wherein X represents silicon and/or germanium and Y represents aluminum, boron, chromium, iron and/or gallium. When X is silicon and Y is aluminum, the new, synthetic zeolite is analogous, in some respects, to the naturally occuring zeolite, levynite. The silica/alumina form of this new crystalline material has a silica to alumina ratio of at least 8 and may be prepared with directing agents which are 2-(hydroxyalkyl) trialkylammonium compounds, dimethyldiethylammonium compounds or cobalticinium compounds. The new crystalline material exhibits a characteristic X-ray diffraction pattern.
