What is the equation for making aspirin?
*The chemical equation corresponding to the synthesis reaction is: C7H6O3 + (CH3CO)2O → C9H804 + CH3COOH.
Is making aspirin exothermic or endothermic?
exothermic reaction
In a reaction vessel salicylic acid, acetic anhydride and sulfuric acid are mixed. The exothermic reaction will cause the temperature to increase to 70-80°C.

How do you make an aspirin sample?
SYNTHESIS OF ASPIRIN (acetylsalicylic acid)
- Place 2.0 g (0.015 mole) of salicylic acid in a 125-mL Erlenmeyer flask.
- Add 5 mL (0.05 mole) of acetic anhydride, followed by 5 drops of conc.
- Heat the flask gently on the steam bath for at least 10 minutes.
- Allow the flask to cool to room temperature.
What is the chemical name for aspirin?
2-Acetoxybenzoic acidAspirin / IUPAC ID
What is the formula for salicylic acid?
C₇H₆O₃Salicylic acid / Formula
Why do we heat aspirin?
Making aspirin In this case just a few drops of sulphuric acid added to the mixture means that there are some free positive hydrogen ions in the solution which can bind to the ethanoic anhydride. This makes it more active and speeds up the reaction. To ensure the reaction goes as quickly as possible we have to heat it.
Is the synthesis of aspirin reversible?
The reaction involves the conversion of a phenol to an ester. This reaction is reversible, which is why aspirin commonly smells of vinegar, as the ASA hydrolyzes in air back to SA and acetic acid.
Does aspirin react with water?
Aspirin (acetylsalicylic acid) reacts with water (such as water in body fluids) to give salicylic acid and acetic acid, as shown in Figure 5.2. 2. Figure 5.2. 2: Hydrolysis of Aspirin reaction.
Why does aspirin react with water?
Aspirin contains polar functional groups which can form hydrogen bonds with polar water molecules. Ionic salts of aspirin, such as sodium acetylsalicylate, are more soluble in water since they form stronger ion-dipole interactions with water.
What is the molecular formula of aspirin?
Aspirin PubChem CID 2244 Structure Find Similar Structures Chemical Safety Laboratory Chemical Safety Summary (LCSS Molecular Formula C9H8O4 or CH3COOC6H4COOH or HC9H7O4 Synonyms aspirin ACETYLSALICYLIC ACID 50-78-2
How to make aspirin from acetic acid?
The most common way to prepare aspirin is by using Acid Anhydrides and by reacting acetic acid with salicylic acid. Learn various other chemical formulas of different compounds at BYJU’S and register now to get complete assistance for the exams.
Is aspirin an ester or esterification?
Aspirin is synthesized by the action of salicylic acid on acetic anhydride. It is an esterification reaction. In this reaction, when salicylic acid reacts with acetic anhydride, the hydroxyl group of salicylic acid converts into an ester group.
Why is aspirin also known as acetylsalicylic acid?
The major component of aspirin is acetylsalicylic acid which gives it all these properties. This is the reason aspirin is also known as acetylsalicylic acid. Its molecular formula is C9H8O4.
