How do you synthesize methyl salicylate?
Take a mixture of 28 g (0.2 mol) of salicylic acid, 64 g (81 ml, 2 mol) of dry methanol and 8 ml of concentrated sulphuric acid in a round bottomed flask of 500 ml. Put a few small chips of porous porcelain, set a reflux condenser to the flask and boil the mixture gently for 5 h.
What is the reaction for methyl salicylate synthesis?
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 is the formula of methyl salicylate?
C8H8O3
Methyl salicylate/Formula
A benzoate ester that is the methyl ester of salicylic acid. Methyl salicylate (oil of wintergreen or wintergreen oil) is an organic compound with the formula C6H4(OH)(CO2CH3).
What are the products of methyl salicylate hydrolysis?
In presence of an acid, methyl salicylate reacts to give salicylic acid and methanol after hydrolysis. Hence, the products of methyl salicylate’s hydrolysis in acid are salicylic acid and methanol.
How is salicylic acid synthesized?
Salicylic acid is produced commercially via the Kolbe-Schmitt process. Here phenol and sodium hydroxide are reacted to make sodium phenoxide. The phenoxide is contacted with CO2 to form sodium salicylate. The salicylate is acidified to give salicylic acid.
What is the empirical formula of salicylic acid?
C₇H₆O₃
Salicylic acid/Formula
What is the mole ratio of methyl salicylate used to salicylic acid produced in part A?
1 mol
When the crystals are thoroughly dry, weigh them and determine the percent yield, based on the amount of starting material. Remember, 1 mol of methyl salicylate yields 1 mol of salicylic acid).

What is the structural formula of salicylic acid?
Salicylic acid/Formula
Structure of Salicylic Acid Its structural formula is C6H4(OH)COOH, which can also be written as C7H6O3 in the condensed form. Its IUPAC name is 2-hydroxybenzoic acid.
How is phenol converted to salicylic acid?
Phenol is converted to salicylic acid by Reimer-Tiemann reaction. When the reaction is carried out in the presence of NaOH and carbon tetrachloride, the product obtained is ortho hydroxyl benzoic acid which is also known as salicylic acid. …
What is the molecular formula for salicylic acid?
Molecular formula of salicylic acid = C7H6O3. Weight of methyl salicylate = 152 g/mole. Weight of salicylic acid = 138 g/mole. Theoretical yield: 152 g of methyl salicylate gives 138 g of salicylic acid. Therefore, 3.5 g of methyl salicylate would give………..
What is the principle of synthesis of methyl salicylate?
Synthesis of methyl salicylate. BACKGROUND. Principle: Methyl salicylate (oil of wintergreen) is an organic ester. When an acid (containing the –COOH group) reacts with an alcohol (a compound containing an –OH group) formed an ester.
How to make salicylic acid from methanol and water?
BACKGROUND. Here one mole of methyl salicylate (oil of wintergreen) reacts with two moles of sodium hydroxide to form sodium-salicylate with methanol and water, each of one mole. Sodium salicylate is reacted with sulfuric acid or hydrochloric acid to remove the sodium ion and forms salicylic acid with sodium sulphate as a byproduct.1.
How to prepare salicylic acid from sodium salicylate?
Sodium salicylate is reacted with sulfuric acid or hydrochloric acid to remove the sodium ion and forms salicylic acid with sodium sulphate as a byproduct. 1. Aim: To prepare salicylic acid from methyl-salicylate by hydrolysis reaction.
