The acetylation of various alcohols and phenols was performed successfully using acetic anhydride in the presence of Citric acid coated magnetite nanoparticles as catalyst under solvent-free condition and at ۴۵ °C. The catalyst showed high thermal stability and was recovered and reused at least ۵ times without any considerable loss of activity. The present process is environmentally benign and economical.
