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")...
