amine that results from the base hydrolysis of acetaminophen
How do you rehydrate acetaminophen?
Record the weight. Recrystallize all but 100 mg of your crude acetaminophen from water by first dissolving the solid in the minimum amount of hot (boiling) water. Do this carefully adding small amounts of hot water. You do not want to have excess water. Work on a steam bath to keep the solution hot. Add another 2 mL of hot water.
Is acetaminophen a weak acid?
Paracetamol (acetaminophen) is a weak acid. The equilibrium position lies very far to the left. The vast majority of paracetamol molecules in an aqueous solution will be found as the undissociated paracetamol molecules.
Which reaction produces an amine and a carboxylic acid?
Hydrolysis (reaction with water) of amides in acidic solution produces an amine and a carboxylic acid. Hydrolysis of paracetamol (acetaminophen) in acidic solution produces an amine (4-aminophenol) and a carboxylic acid (acetic acid)
What acetaminophen is soluble in water?
The Merck Index, which is an encyclopedia of chemicals, drugs, and biologicals, lists the following information under acetaminophen: large monoclinic prisms from water, mp 169-170.5, very slightly sol in cold water, considerably more soluble in hot water. Sol in methanol, ethanol, dimethylformamide, acetone, ethyl acetate.
