PRELAB EXERCISE EXPERIMENT 21 Synthesis of Aspirin (Acetylsalicylic Acid) What is the purpose of sulfuric acid or phosphoric acid used in the acetylation reaction? Use equations to explain this purpose. The procedure calls for cautious addition of water to the reaction mixture while it is still hot. What purpose does the addition of water serve and why should the addition be done while the reaction mixture is hot? Provide an equation for the reaction involved.Using the quantities of salicylic acid and acetic anhydride...

EXPERIMENT 20 CSI: SMU Part 2. Synthesis of an Ester. Esters are compounds of the form RCOOR'. They occur naturally in many plants and animals, and can be synthesized. They have a pleasant aroma usually described as "fruity of flowery". In a Fisher esterification an ester is formed from the reaction of a carboxylic acid and an alcohol with a strong acid as a catalyst. The OH contained in the carboxylic acid group 1s replaced with the alkoxy group (O-R")...
