Preparation of Synthetic Banana Oil Introduction: In this lab the synthesis‚ purification‚ and characterization of isoamyl acetate‚ or banana oil‚ was determined. The synthesis was completed by a reversible esterification reaction which required the heating of glacial acetic acid and isoamyl alcohol‚ combined with a sulfuric acid catalyst in hexane. In order to increase the efficiency of the reaction‚ LeChatelier’s Principle is utilized by removing water from the products. As a result‚ the reaction
