Friedel-Crafts acylation of aromatic compounds over hybrid zeolitic-mesoporous materials

摘要：

Microporous-mesoporous materials were synthesized by a two step process, based on the assembling of ZSM-5 precursors around CTAB micelles. The solids, named HZM, were characterized by XRD, FT-IR, TEM, N2 adsorption-desorption isotherms, TG and NH3 TPD analyses, exhibiting properties intermediate of those of Al-MCM-41 and ZSM-5 materials. The HZM samples have been tested in acylation of anisole and 2-methoxynaphtanlene, showing higher catalytic activity than both amorphous mesoporous Al-MCM-41 and crystalline ZSM-5. Selectivity towards the isomers of interest was favoured by the use of acetyl chloride as acylating agent.
