NAME: Micaiah Millington DATE: 5/16/19 AP CHEMISTRY MS. KUTI SYNTHESIS OF ASPIRIN LAB REPORT BACKGROUND : The purpose of this lab was to create aspirin. We used the method of reacting salicylic acid with acetic anhydride and and a trace amount of acid. A substance is considered an organic compound in chemistry if it contains carbon. Functional groups play an important part in the formation of the molecules. When making aspirin, salicylic acid and acetic anhydride react together to produce acetylsalicylic acid and acetic acid. Aspirin is a very popular product in the pharmaceutical industry because it is both an analgesic and antipyretic which is a painkiller and reduces fevers. MATERIALS AND PROCEDURE : 1. Salicylic acid 2. 125 mL Erlenmeyer flask 3. Hot plate 4. Ice Water Bath 5. Acetic anhydride 6. H 2 SO 4 (sulfuric acid) 7. 500 mL Beaker 8. Filter Paper 9. Graduated Cylinders 10. Glass rod 11. Funnel Fill the 600 mL beaker halfway with water and then heat up the water in the beaker until it gets to a temperature of 80°-90°. When waiting for the water to heat up, weigh out 3.00 g of salicylic acid and place it in a 125 mL Erlenmeyer flask. Write the weight on the data table.Get a graduated cylinder, add 6 mL of acetic anhydride into the Erlenmeyer flask. Add 5 drops of sulfuric acid into the flask. Mix the reagents in the flask carefully by swirling the flask. Place the Erlenmeyer flask into the hot water bath for ten minutes. MAKE SURE THE TEMPERATURE OF THE WATER REMAINS BETWEEN 80°-90° C THROUGHOUT THE ENTIRE TIME. After ten minutes, remove the Erlenmeyer flask and allow it to cool to room temperature for about 5 min. Add 40 mL of distilled water into the flask and then place the flask in a cold ice water bath so that the product can crystallize into a solid. Pour the crystals on a filter paper using the a funnel and slightly wash the crystals with cold water using a deionized water bottle. Let the crystals dry overnight then weigh the product the next day.
