Lab #12 Isopentyl Acetate. Abstract A % yield of isopentyl acetate was obtained via an acid catalyzed nucleophilic acyl substitution with 5 milliliters of isopentyl alcohol and 7 milliliters of acetic acid in the presence of an acid catalyst.

Elizabeth Ping November 29, 1 Isopentyl Acetate Banana Oil Introduction: The purpose of this experiment was to prepare the ester that smells like bananas, isopentyl acetate lab report, isopentyl acetate by using the techniques of reflux, extraction, drying, and distillation.

Set up. Observations: Calculations: Mass of 5 mL conical vial In this experiment, 0. Sulfuric acid was used as a catalyst in the reaction. An excess of isopentyl acetate was used to shift the reaction to the right so that esterification could occur. During isolation, the excess acetic acid and isopentyl alcohol was removed with sodium bicarbonate, isopentyl acetate lab report, and the isopentyl acetate was further purified after through drying with anhydrous sulfate and through distillation.

The percent yield of the isopentyl acetate was In the experiment, the acetic acid was in excess and the isopentyl alcohol was the limiting reagent, and therefore, the reaction depended on the amount of isopentyl alcohol available.

This experiment was a partial success since the smell of bananas was achieved despite the lower percent yield attained of Some of the errors that might have occurred included using unclean glassware that may have produced side reactions and water may not have circulated fast enough during reflux and distillation. Questions: 1 The excess acetic acid was used in order for the reaction to favor esterification. An excess of isopentyl alcohol could have been used instead to form isopentyl acetate, however isopentyl alcohol is more expensive and more difficult to use.

Elizabeth Ping November 29, 4 3 Isopentyl acetate lab report sodium carbonate is a base, it is used in the extraction of acetic acid because it turns acetic acid into a conjugate base isopentyl acetate lab report sodium acetate which is more soluble in water.
