esters
Experiment #3: The Fischer EsterificationDates: February 1, 2001- EsterificationOrganic compounds that are classified into the ester group are commonly Associated with very pleasant smelling fragrances. These esters can be synthesized by combining a carboxylic acid with an alcohol while using a mineral catalyst. By causing a reaction between ethanoic acid, more commonly known as acetic acid, and 3-methyl-1-butanol or isopentyl alcohol, the ester isopentyl acetate (3-methyl-1-butyl ethanoate) is produced. Isopentyl acetate is easily recognizable by the strong, "banana," odor. This ester is used to give perfumes, foods, and beverages their fragrance and is a major component of banana oil. In order to synthesize isopentyl acetate, glacial acetic acid undergoes esterification with isopentyl alcohol. Before the process of esterification can begin, the starting material acetic acid must be obtained. Acetic acid can either be found naturally or produced synthetically. In nature, this acid is found as a product of the oxidation of ethanol. Acetic acid is th
The spectra results of the isopentyl acetate produced in class proved to be very similar to those found in Sadtler. Also, the set of experimental conditions must be the same. Results and Discussion Initially, the only thing given concerning the synthesis of the product was the structure and it's respective common name. As each of the components of the ester went through the column, peaks were recorded in order to calculate the retention time. Acetic acid dissolves most simple organic compounds, and it has a convenient boiling point (118 C). The alkyl carbon-hydrogen, part of the compound is represented by a peak around 2900 cm-1 on the spectra. In order for this reaction to take place, a catalyst was required so sulfuric acid was used. ------------------------------------------------------------------------**Bibliography**. The starting products to form ester were isopentyl alcohol and glacial acetic acid. Since the process for forming isopentyl acetate is being practiced worldwide, maybe the best procedure in order to form a surplus of the product will be discovered so that research concerning other uses of isopentyl acetate will be able to be performed. This can be done by running a Gas chromatography (GC), a Nuclear Magnetic Resonance Spectrometry (NMR), and an infrared spectrometry (IR).
