CHY 123 Synthesis of Aspirin Introduction Aspirin has been around for hundreds of years as a painkiller. It used to be made from an extract of the willow tree bark until the late 19 th century when its active ingredient, Acetylsalicylic acid¸ was isolated. Today Acetylsalicylic acid is synthetically formed by reacting salicylic acid and acetic anhydride. Procedures We gathered the needed chemicals and containers needed for the experiment. We then weighed out 10.006g of the Salicylic acid into a beaker and added 15 mL of acetic anhydride and about 5 drops of concentrated Sulfuric acid. We then heated this solution to about

Unformatted text preview: 60 C. we then added about 150ml of distilled water to the beaker and began to filter it through the filter paper. After it was basically dry, we weighed it out and then put it into the desk to dry for next week. Discussion After reviewing the data gathered from the experiment we found that we should have produced about 13.04g of aspirin. After gathering the data from the next week we found that we actually produced 10.26g. This gave us a 78.68% yield. The most likely cause of this discrepancy was due to human error when we were filtering the solution the week before....
