ZrCl 4 ‐Mg ( ClO 4 ) 2 : Highly efficient bimetallic catalyst for acetylation of alcohol with acetic acid

This work describes the highly efficient acetylation (acylation) of alcohols with acetic acid for the ester synthesis in the presence of newly designed a new composite zirconium (IV) chloride and magnesium catalyst which is used bimetallic acidic catalyst ZrCl 4 ‐Mg(ClO 4 ) 2 , which is formed by grinding ZrCl 4 and Mg(ClO 4 ) 2 in the molar ratio of 1:2, respectively. Thus, the powder X‐ray diffraction, scanning electron microscopy, Brunauer–Emmett–Teller surface area, and thermogravimetric analysis of the ZrCl 4 , Mg(ClO 4 ) 2 , and non‐calcined ZrCl 4 ‐Mg(ClO 4 ) 2 were recorded. In each case, structural analysis was carried by grinding the catalyst in mortar and pestle.
