A synthetic porous crystalline material has a composition, on an anhydrous basis and in terms of moles of oxides, expressed by the formula:… (0-5)M2/nO:(0.02-0.2)Al2O3:(100)SiO2… wherein M is at least one cation having the valence n, and has a characteristic X-ray diffraction pattern exhibiting values substantially as set forth below: …<IMAGE>… …<??>The new zeolite is produced from an aqueous reaction mixture containing sources of the required oxides and organic cation derived from a diethylated, linear diquaternary compound having the formula… X(CH3)2(C2H5)N(CH2)4N(C2H5)(CH3)2X… wherein X is an anion. |
