benzyl chloride is boiled under a reflux condenser with an excess of a 10 %, potassium carbonate solution for 12 hours. When the reaction is complete and the smell of the benzyl chloride has disappeared the reaction mixture is cooled and extracted with Ether. The Ether extract is dried with potassium carbonate or sodium sulfate, and then removed by evaporation. The benzyl alcohol is purified by distillation collecting fraction which passes over at 206° C and forms a colorless liquid.
