How is the process of making aspirin carried out in pharmaceutical manufacturing?

The process of making aspirin in pharmaceutical manufacturing involves combining salicylic acid with acetic anhydride in the presence of a catalyst, such as sulfuric acid. This reaction forms acetylsalicylic acid, which is the active ingredient in aspirin. The mixture is then purified, crystallized, and dried to produce the final aspirin product. Quality control measures are implemented throughout the process to ensure the purity and consistency of the aspirin tablets.
