Carboxylic group (-COOH) converts into ester (−COCH3) during the reaction of salicylic acid with methanol so, reaction is known as esterification.
The product methyl 2− hydroxyl benzoate is known as the oil of wintergreen. Oil of wintergreen is naturally produced organic ester.
1) Methyl salicylate (oil of wintergreen)
Salicylic acid and methanol undergo esterification reaction in presence of acid catalyst to give methyl salicylate and water.
Salicylic acid is odorless and white Solid Methanol is colourless volatile liquid having pungent odour or smell. Methyl salicylate is colourless liquid having sweet and fruity smell
