Molybdenum-modified mesoporous SiO₂ as an efficient Lewis acid catalyst for the acetylation of alcohols.

ABSTRACT: A suitable, expeditious and well-organized approach for the acetylation of alcohols with acetic anhydride in the presence of 5%MoO₃-SiO₂ as an optimum environmentally benign heterogeneous catalyst was developed. The high surface area obtained for 5%MoO₃-SiO₂, 101 m² g^-1 compared to other catalysts, 22, 23, and 44 m² g^-1 for 5%WO₃-ZrO₂, 5%WO₃-SiO₂, and 5%MoO₃-ZrO₂, respectively, appears to be the driving force for better catalytic activity. Amongst the two dopants used, molybdenum oxide is the better dopant compared to its tungsten oxide counterpart. High yields of up to 86% were obtained with MoO₃ doping while WO₃ co
