    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.

    Benzyl alcohol is prepared by the hydrolysis of benzyl chloride using sodium hydroxide.C6H5CH2Cl + NaOH → C6H5CH2OH + NaCl

    It can also be prepared by a Grignard Reactionby reacting phenylmagnesium Bromide  (C6H5MgBr) with formaldehyde, followed by acidification.
