Simple, gas chromatography preparation of synthetic banana oil kate manning conducted: 1/31/12 submitted: 2/14/12 introduction: the purpose of this experiment was to synthesize banana oil from the reaction of acetic acid and isopentyl alcohol to form isopentyl acetate. Fractional distillation and gas chromatography background in a simple distillation, you condense the vapor that boils off and collect it as a gas chromatography. (1) set the heating mantle and reflux condenser up on a lab jack, in preparation of converting to the simple distillation later in the lab water-cool the reflux condenser (2) once reflux begins (set the heating mantle control to ~75, and adjust from there), allow the reaction to proceed for 45 minutes, prior to switching to simple distillation.
