How do you make aspirin in chemistry?

SYNTHESIS OF ASPIRIN (acetylsalicylic acid)

1. Place 2.0 g (0.015 mole) of salicylic acid in a 125-mL Erlenmeyer flask.
2. Add 5 mL (0.05 mole) of acetic anhydride, followed by 5 drops of conc.
3. Heat the flask gently on the steam bath for at least 10 minutes.
4. Allow the flask to cool to room temperature.

What elements make up aspirin?

The chemical name of aspirin is acetylsalicylic acid. By looking at its chemical structure, you’ll see that it’s composed of three different types of atoms: carbon, hydrogen, and oxygen.

How is aspirin prepared give equation?

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.

How do you increase aspirin yield?

In a reflux reaction with aspirin, the best yield should be obtained by heating the mixture of reactants around above the solvents boiling point. This will allow for optimal heat and higher rate of collisions during reaction, allowing more product to be produced.

Is aspirin element or compound?

2-Acetoxybenzoic acid
Aspirin/IUPAC ID

What is aspirin chemistry?

One of the best known aromatic acetates is acetylsalicylic acid, or aspirin, which is prepared by the esterification of the phenolic hydroxyl group of salicylic acid. Aspirin possesses a number of properties that make it the most often recommended drug. It is an analgesic, effective in pain relief.

How do I prepare aspirin for Class 12?

Synthesis of Aspirin/Acetylsalicylic acid (C9H8O4)

1. Step 1: Dry an Erlenmeyer flask and add 3 grams of salicylic acid to it.
2. Step 2: Put 5 to 8 drops of 85% phosphoric acid along with 6 mL of acetic anhydride to the flask.
3. Step 3: Mix the solution and keep the flask in warm water for 15 minutes.

What tree is used to make aspirin?

The story of the discovery of aspirin stretches back more than 3500 years to when bark from the willow tree was used as a pain reliever and antipyretic.

Can you make aspirin from a weeping willow tree?

The active ingredient in the medicine made from willow bark is called salicin. Some people use willow bark as an alternative to aspirin, particularly those that experience chronic headaches or back pain.

How do you make aspirin with salicylic acid?

To prepare aspirin, salicylic acid is reacted with an excess of acetic anhydride. A small amount of a strong acid is used as a catalyst which speeds up the reaction. In this experiment, phosphoric acid will be used as the catalyst. The excess acetic acid will be quenched with the addition of water.

What happens to the methanol produced when making aspirin?

Methanol is the alcohol which is released by hydrolysis. Second, the hydroxyl group on salicylic acid will be used in ester formation to produce aspirin. As a result, the thermodynamic equilibrium will now be for the formation of an ester instead of its hydrolysis.
