In this lab we created aspirin. We used salicylic acid and acetic anhydride to make aspirin. Sulfuric acid was the catalyst. We split the lab into 2 days. In day 1, we measured out 5 grams of salicylic acid. To this we added 7 ml of acetic anhydride, Then we added 8 drops of sulfuric acid with a simple pipette. After this we mixed the contents using a stirring rod. Then we heated the mixture using a hot water bath and a hot plate. We heat the mixture for 15 mins after it begins to boil. When the mixture is heated, acetylsalicylic acid and acetic acid is formed. After this we cool the mixture by removing it from the hot plate and placing it on a hot pad. After 3 mins, we slowly add 15 ml of ice cold water to the flask to remove the excess acetic anhydride. Then we poured the contents into a smaller beaker and covered it with a post it and let is sit overnight. This is the end of Day 1 of the aspirin lab.
