Aspirin to Acetaminophen - Part 6 of 6: Acetaminophen from p-aminophenol
This is the final part of the series, where the p-aminophenol is converted to the acetaminophen. Using acetic anhydride, the p-aminophenol is going to be acetylated. The reaction is carried out in water at room temperature. Acetic anhydride does react with water, but it happens slowly.

Acetaminophen/Paracetamol (Tylenol)
Acetaminophen, more commonly known by brand names such as Tylenol, is not a true NSAID, as it does not have anti-inflammatory properties. However, it is commonly discussed alongside NSAIDs as it has similar antipyretic and analgesic properties. Although its mechanism of action is not well-

How to extract Acetylsalicylic Acid from Aspirin Tablets
Acetylsalicylic is readily available in Aspirin tablets. Chemically, it is a useful molecule. It can be converted to salicylic acid and then phenol, which is an extremely useful precursor. Also, the salicylic acid itself can be used to make the minty smelling wintergreen. All in all, ace
