A suitable, expeditious and well-organized approach for the acetylation of alcohols with acetic anhydride in the presence of 5%MoO-SiO as an optimum environmentally benign heterogeneous catalyst was developed. The high surface area obtained for 5%MoO-SiO, 101 m g compared to other catalysts, 22, 23, and 44 m g for 5%WO-ZrO, 5%WO-SiO, and 5%MoO-ZrO, 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.

Heterogeneous catalysts have found use in many industrial processes by virtue of their ease of separation and high activities in various reactions. However, many processes employing heterogeneous catalysts in the transformation of organic molecules suffer significantly when it comes to product selectivity.
