Add an excess of methanol to 8.0g of benzoic acid followed by a few drops of concentrated sulfuric acid. Cool the mixture, pour into a separating funnel and add a similar volume of cyclohexane. Wash the cyclohexane layer left in the separating funnel with sodium carbonate solution. Vigorously shake the mixture, allow to settle. Run off the lower layer. Run off the cyclohexane layer into a conical flask and allow to stand over Distil the cyclohexane layer collecting the distillate above 190 °C. solid anhydrous sodium sulfate and then filter.
