摘要

Mesoporous Al-MCM-41 (Si/Al= 55 and 104) and Al, Zn-MCM-41 (Si/(Al+ Zn)= 52) molecular sieves were synthesized hydrothermally. The materials were characterized by XRD, TGA, TPD (pyridine), ICP-AES, nitrogen sorption, and FT-IR techniques. The catalytic performance of these materials was examined in the vapor phase alkylation of m-cresol with isopropyl acetate. The products obtained were thymol, isothymol, 2-isopropyl-5-methylphenyl ...
