What happens when salicylic acid is treated with methanol?
The carboxylic group (-COOH) converts into ester (−COCH3) during the reaction of salicylic acid with methanol so, the reaction is known as esterification. The product methyl 2− hydroxyl benzoate is known as oil of wintergreen. Oil of wintergreen is a naturally produced organic ester.

What does ethanol and salicylic acid make?
Ethyl salicylate is the ester formed by the condensation of salicylic acid and ethanol. It is a clear liquid that is sparingly soluble in water, but soluble in alcohol and ether. It has a pleasant odor resembling wintergreen and is used in perfumery and artificial flavors.
Is salicylic acid soluble in methanol?
For example, the solubility of salicylic acid amounts to 2.56 mol L -1 and 2.25 mol L -1 in methanol and ethanol at 298.15 K [15]. ...
How is salicylic acid converted to methyl salicylate?
When salicylic acid is heated with methyl alcohol, the carboxyl group of salicylic acid is esterified producing a strong-smelling liquid ester (methyl salicylate). an alcohol and a carboxylic acid. The reaction is reversible and uses an acid as a catalyst.
What does methanol and salicylic acid smell like?
It is the methyl ester of salicylic acid. It is a colorless, viscous liquid with a sweet, fruity odor reminiscent of root beer, but often associatively called "minty", as it is an ingredient in mint candies. It is produced by many species of plants, particularly wintergreens.
Does alcohol react with salicylic acid?
The major use of salicylic acid is in the preparation of its ester derivatives; since it contains both a hydroxyl (−OH) and a carboxyl (−CO2H) group, it can react with either an acid or an alcohol.
What does methyl salicylate do?
This product is used to treat minor aches and pains of the muscles/joints (such as arthritis, backache, sprains). Menthol and methyl salicylate work by causing the skin to feel cool and then warm. These feelings on the skin distract you from feeling the aches/pains deeper in your muscles and joints.
What reacts with salicylic acid?
However, salicylic acid also has an electrophilic carbon atom as part of its carboxylic acid functional group. Thus, salicylic acid can react with nucleophilic molecules like methanol in addition to reacting with electrophilic molecules like acetic anhydride.
Why does salicylic acid dissolve in ethanol?
The solubility of salicylic acid decreases in the order of ethanol, ethyl acetate, carbon tetrachloride, xylene, and water. The low cohesive energy of the solvent may relate to high solubility in ethanol and ethyl acetate.
Is salicylic acid soluble in alcohol?
Solubility. Salicylic acid has an aqueous solubility of about 2.2 mg/mL. In boiling water, the solubility increases to about 67 mg/mL. In ethanol, the solubility is about 333 to 370 mg/mL.
How is salicylic acid converted into aspirin?
For the preparation of aspirin, salicylic acid is reacted with an excess of acetic anhydride. Small amount of strong acid is used as a catalyst in these reactions which enhances the speed of reaction acid used is phosphoric acid. Excess acetic acid will be extinguished with the addition of water.
