Synthesis of Aspirin Learning Goals 1. To synthesize aspirin from salicylic acid and acetic anhydride. 2. To purify the crude product by Recrystallization. Introduction Most drugs are chemical compounds which are described as "organic compounds" because they are comprised primarily of the elements carbon‚ hydrogen and oxygen. The present experiment will be the synthesis of a familiar organic compound called aspirin. The common chemical name is acetylsalicylic acid. Aspirin‚ the
