Reaction time required for this method is very short phenol price yield of about 77%. Another method of operation of phenol and acetic anhydride is heated to boiling under reflux for 3h, successively washed with water, caustic washing, cleaning phenol polyester resin was cooled, dried over anhydrous sodium sulfate, and distilled to collect 190-195 ℃ fraction, Good for phenyl acetate.
