| 摘要 |
This invention relates to a new synthetic porous crystalline material, designated MCM-71, a method for its preparation and its use in catalytic conversion of organic compounds. The new crystalline material exhibits a distinctive X-ray diffraction pattern and has a unique 3-dimensional channel system comprising generally straight, highly elliptical channels, each of which is defined by 10 membered rings of tetrahedrally coordinated atoms, intersecting with sinusoidal channels, each of which is defined by 8-membered rings of tetrahedrally coordinated atoms. |
