aMicroscale Synthesis of Isopentyl Acetate (Banana Oil) Objective: Carried out the microscale synthesis of isopentyl acetate by direct esterification of acetic acid and isopentyl alcohol. This was an acid catalyzed Fischer esterification. Both extraction and distillation were employed to obtain a pure product. IR spectroscopy and gas chromatography were used to determine purity of the final product. Reagents: * Compound: | * MW (g/mol): | * MP (°C): | * BP (°C): | * Density (g/mL):
