Experiment Four: Organic Synthesis of Aspirin Abstract The purpose of this experiment is to synthesize a common organic product called acetylsalicylic acid (aspirin)‚ and to become familiar with the optimum conditions needed for successful yields. Aspirin is produced from an acid catalyzed reaction between salicylic acid with acetic anhydride. The crystalline aspirin is synthesized and purified by recrystallization‚ although there is not a hundred percent yield due to sources of error. Introduction
