Synthesis of aspirin lab

Half-fill a second mL beaker with crushed ice and water to use as an ice bath. Hoffman's father had severe arthritis but could not tolerate salicylic acid he was taking for pain relief. Add an additional 5—6 mL of ice-cold water to the Erlenmeyer flask and place the flask in the ice bath step 8 to allow the aspirin to crystallize. Formation of an iron-phenol complex with Fe lll gives a definite color ranging from red to violet, depending upon the particular phenol present. Crystals should form. Rinse the filter flask with water and discard the rinse water into the waste container under the hood. Using a weigh boat, weigh out 5. Air dry the crystals and transfer them to a watch glass to dry. Note: The density of acetic anhydride is 1. Friedrich Bayer, the employer of Hoffman, patented the name and began marketing the product in

Keep the flask in the ice-water bath for 10 minutes to complete crystal formation. Cooling The Reaction Mixture A. Test this crude product for the presence of unreacted salicylic acid using the ferric chloride test.
