AbstractMesoporous aluminosilicates with cubic and hexagonal structure have been synthesized by structure units of beta-zeolite in a two-step crystallization process and characterized by XRD, IR, N-2 physical adsorption and desorption, Al-27 MAS NMR and NH3-TPD techniques. The results show that MB48(25) and MB41(25) were similar to MCM-48 and MCM-41 on the long-range structure respectively and MB48 with a cubic, structure can be synthesized. under the condition of a lower n(CTMAB)/n(SiO2) ratio. HMB48 (25) and HMB41 (25) exhibit a stronger acidic strength than conventional HMCM-41. The catalytic activity of HMB48(25) was the highest for cumene cracking and alkylation of 2,4-tert-butylphenol with tert-butylalcohol.
