Acetylsalicylic Acid

OBJECTIVES
The objective of this lab experiment is to prepare aspirin (acetylsalicylic acid) by reacting salicylic acid and acetic anhydride.
INTRODUCTION
This purpose of this lab was to prepare aspirin using its basic components: salicylic acid and acetic anhydride. Salicylic acid and acetic anhydride, along with an acid catalyst, react to form acetylsalicylic acid (aspirin) and acetic acid. In this reaction, the hydroxyl group on the benzene ring in salicylic acid reacts with acetic anhydride to form an ester functional group. The acetylsalicylic acid crystallizes as the solution cools and begins to come out of the solution. The acetylsalicylic acid is further purified through recrystallization with ethyl acetate.
MATERIALS USED:
Test Tubes Pasteur Pipette
Salicylic acid acetic anhydride
Sulfuric acid 125 mL Erlenmeyer flask
Scale Water Hot water bath
Ice Bath Buchner Fünnel
1% Ferric Chloride......
