Gather materials and wear safety gear.
In a beaker, combine salicylic acid and acetic anhydride.
Add a drop of sulfuric acid as a catalyst.
Heat the mixture gently while stirring for 10-15 minutes.
Allow the mixture to cool, then pour it into an ice bath.
Filter the precipitate to collect aspirin crystals.
Dry the crystals and record the yield.
Analyze the purity and characteristics of the synthesized aspirin.
It is expected that aspirin will be successfully synthesized, demonstrating the esterification process and yielding a product that can be analyzed for purity.
