Abstract
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.
