Explain what is the purpose of the following reagents/procedural steps in the synthesis of acetaminophen by reacting p-aminophenol with acetic anhydride: a. Phosphoric acid b. Placing the reaction flask in warm water c. Purpose for placing crude product of acetaminophen in a 100 ml beaker with 20 ml of water, then heat it on a hot plate until crystals dissolves then let cool. Then having it in an ice bath for 20 min once crystals appeared. d. Drying product at...

the synthesis of acetaminophen was performed. what mechanism occurs to go feom p-Aminophenol to Acetaminophen (substitution. addition, or elimination)?. Draw the mechanism using p-Aminophenol, acetic anhydride, acetominophen, and acetic acid. Is p-Aminophenol the ami r or the amide? Is Acetaminophen an amine or amide ?

EXPERIMENT 19 PREPARATION OF ASPIRIN In addition to the Fischer esterification method presented in Experiment 18, a second method for preparation of esters involves the reaction of anhydrides with the hydroxyl This method is ospecialy usoful for tho preparation of acetate esters, since acetic anhydride is an inexpensive and reactive reagent. In this experiment the hydroxyl group of salicylic acid is acetic anhydride to make acetylsalicylic acid, or aspirin. The short...

Please help me solve this and show the full calculations. Calculate the limiting reactant, theoretical yield, and percent yield using the following: 2.0 g of salicylic acid and 5 mL of acetic anhydride, along with 10 drops of phosphoric acid, were used to make acetylsalicylic acid. This is a 1:1 mole ratio.
