PDF	O-ACYLATION MECHANISM OF p-SUBSTITUTED PHENOLS WITH Thus this acylation process involves a competition among the formation of PA and the hydrolysis of acetyl chloride as well as that of the ester formed However

Why is acetic anhydride preferred over acetyl chloride for acetylation reaction?
(iii) Acetyl chloride is more reactive and hence more liable to undergo side reaction.
Therefore acetic anhydride is preferred for acylation.
How does phenol react with acetyl chloride?
When Phenol reacts with Acetyl chloride ( CH 3 COCl ), it forms Phenyl acetate along with hydrochloric acid.
Making esters from phenol using an acyl chloride
Phenol reacts with ethanoyl chloride at room temperature, although the reaction isn't as fast as the one between ethanoyl chloride and an alcohol.
Phenyl ethanoate is formed together with hydrogen chloride gas.
