Synthesis of Methyl salicylate

Set up for a reflux apparatus. Pour 150 mL of methanol, 45 g of salicylic acid and slowly with mixing 30 mL of sulfuric acid. Start heating the mixture at 95°C for 4h. Remove 70 mL of the methanol with a rotary evaporator, pour the mixture into a separatory funnel and wash it with 100 mL of ice-cold water. Wash the solution with 100 mL of 20% sodium carbonate solution and collect the bottom layer. Dry it with a drying agent and distill it at 224°C.
