Aim To prepare a sample of aspirin and to calculate the percentage yield of product obtained Objective To react salicylic acid with acetic anhydride to produce acetylsalicylic acid and determine it percentage yield. Introduction 2-Acetoxybenzoic acid, more commonly known as Aspirin, is a white, crystalline Substance most commonly known for its pain-relieving qualities. Acetylsalicylic acid (active ingredient of Aspirin) is an acetyl derivative of salicylic acid and the prodrug of the active metabolite, salicylic acid. Aspirin is a salicylate drug because it is an ester of salicylic acid. It is commonly known for its pain relieving properties. However, it does not only serve as an analgesic but also as an antipyretic, anti- inflammatory, and antiplatelet medication. The main metabolite of acetylsalicylic acid, salicylic acid, is an essential part of the human metabolism. Salicylic acid is an integral part of pain management and was often used by ancient cultures, such as the Native Americans, who extracted the chemical from willow tree bark. This fundamental compound can cause stomach irritation and is bitter tasting, so a milder prodrug called acetylsalicylic acid was synthesized in 1893 by the German chemist Felix Hoffmann who worked for Bayer.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
