摘　　要：A new method has been developed for the chemoselective acetylation of alcohols with acetic anhy‐dride in the presence of phenols using a novel,recyclable Cu O‐Zn O nanocatalyst.The catalyst was synthesized using the co‐precipitation method and characterized by N2 adsorption‐desorption,X‐ray diffraction,scanning electron microscopy,transmission electron microscopy and energy dis‐persion scanning analyses.Furthermore,this catalyst could be recycled up to six times without significant loss in its activity.A new method has been developed for the chemoselective acetylation of alcohols with acetic anhy‐dride in the presence of phenols using a novel,recyclable Cu O‐Zn O nanocatalyst.The catalyst was synthesized using the co‐precipitation method and characterized by N2 adsorption‐desorption,X‐ray diffraction,scanning electron microscopy,transmission electron microscopy and energy dis‐persion scanning analyses.Furthermore,this catalyst could be recycled up to six times without significant loss in its activity.
