Synthesis of zeolites using N,N'-tetramethylen-bis-(N-methylpiperidinium)dihydroxydes as directing agent

摘要

The synthesis of two new materials referred to as ERS-13 and ERS-14 has been obtained using N,N'-tetramethylen-bis-(N-methylpiperidinium)dihydroxydes(M4BP(OH)2)as structure directing agent.The new phases were characterized by X-Ray Diffraction and Transmission Electron Microscopy.ERS-13 is most likely a layered material with a structure close to the previously reported ITQ-8.ERS-14 is a disordered zeolite material,and,similarly to zeolite ITQ-10 and ITQ-16,belongs to the family of zeolite beta.However,ERS-14 shows a weak XRD peak at 3.8° of 29(1=1.54178 A)never reported,testifying a periodicity of 23.6A.
