) and allow the flask and contents to cool on the lab bench for about 3 minutes. After the flask has cooled for about 3 minutes, CAUTIOUSLY add 15 m L of room temperature water to the flask to facilitate the decomposition of the excess acetic anhydride. Be sure to seat the filter paper in the filter with a small amount of water. Rinse the flask twice with 3 m L of ice cold water to remove any residual crystals. Discard the filtrate left in the filter flask into the waste container under the hood. Transfer as much of the solid as possible from the Buchner funnel to a clean, dry 250 m L beaker. Add 10 m L of 95% ethanol to the beaker and if necessary, warm (do not boil!
Place the aspirin onto a doubled piece of paper towel and set aside to dry while performing the qualitative analysis of the aspirin.
Hoffman's father had severe arthritis but could not tolerate salicylic acid he was taking for pain relief.
The name given for Hoffman's new compound was A-spirin.
The salicylic acid and aspirin may cause irritation to your skin or eyes, but are basically not hazardous.
An excess of these can be disposed of in the sink or, if packaged, in the trash.
