Esterification of Benzocaine By: Nick Makowski and Monica Schaeffer Purpose: To practice the techniques of refluxing and vacuum filtration to perform an esterification reaction to create benzocaine from p-aminobenzoic acid Chemical Structures/Reactions/Mechanisms: Results: Physical Appearances- After ethanol and sulfuric acid added to p-aminobenzoic acid, solution became clumpy and then turned into a white foam After refluxing, solution became more solid Upon filtration, white benzocaine crystals formed Mass of Substances- p-aminobenzoic acid: 1.201g benzocaine: 0.368g Na2CO3: 11mL Melting Point- Known= 88-90 […]
