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 (SiO 2) 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.展开更多
