What are some interesting facts about the synthesis of aspirin?
Synthesis of Aspirin. The main objective of the synthesis of aspirin lab was so produce aspirin (acetylsalicylic acid) through the reaction of salicylic acid and acetic anhydride. The methods used included recrystallization and scratching to produce a precipitate, which was then filtered to remove any excess moisture.
What is the product of the reaction between aspirin and acetic anhydride?
The synthesis of aspirin is classified as an esterification reaction. Salicylic acid is treated with acetic anhydride, an acid derivative, causing a chemical reaction that turns salicylic acid's hydroxyl group into an ester group (R-OH → R-OCOCH 3). This process yields aspirin and acetic acid, which is considered a byproduct of this reaction.
What is a byproduct of the reaction between aspirin and sulfuric acid?
This process yields aspirin and acetic acid, which is considered a byproduct of this reaction. Small amounts of sulfuric acid (and occasionally phosphoric acid) are almost always used as a catalyst. This method is commonly employed in undergraduate teaching labs.
What is the role of a catalyst in the synthesis and characterization of aspirin?
Synthesis and Characterization of Aspirin. A catalyst is something that changes the rate of a reaction, but is not actually consumed in the reaction itself. In this experiment, the catalyst of Phosphoric Acid is used to catalyze the formation of Aspirin, which can be seen in the mechanism of the reaction in Figure 2.
