LAB 9: Preparatin of synthetic Banana oil
NAME: VINCENT NSIAH
TA: JEREMIAH KARANJA
DATE: NOVEMBER 16TH, 2013
Abstract The purpose of this lab was to determine whether a sufficiently pure sample of synthetic banana oil could be prepared through Fisher Esterification. During the experiment, the reaction mixture was purified through an extraction workup, and according to the instructor, once getting the density of the product and the actual yield; it was not required to use the distillation method.
Introduction
Banana oil as an artificial flavoring in the food industry is immense. Synthetic Banana flavorings can be used as a substitute for natural banana flavoring in the events that banana tree crops are damage or in limited supply. It is very important that the artificial banana flavoring be synthesized in such way that the product has a high level of purity. Fisher esterification is a process whereby an ester is prepared, and involves heating a carboxylic acid with an alcohol in the presence of an acid catalyst, which is used to expedite the reaction. In this experiment the process was used to synthesis isopentyl alcohol, which was the limiting reagent, with sulfuric acid and excess of acetic acid. Had equal amounts of acetic acid and isopenthyl alcohol been used, approximately only two thirds of each would be converted to acetate. This mixture was heated under reflux for one hour to ensure that the reaction went to completion.
Chemical reaction
Safety
Refer to the lab handout, which can be found on UB learns page 4.
Procedure
See lab note, which can be found in TA notes from Recitation pages (19-22) and Lab handout, which can be found on UB learns pages (6-9)
Experimental
Fischer esterification was used in this experiment in order to synthesis isopenthyl acetate. This process involved combining
