[PDF] fischer esterification percent yield

What is the yield of Fischer esterification reaction?

Based on a comparison with other IR spectra databases, the spectrometer determined that 935 times out of 1000, the product was the ester 3-methylbutyl ethanoate. The Fischer Esterification reaction is driven by shifts in equilibrium; therefore the yield of the desired ester can never be 100%.

What is a Fischer ester?

The Fischer Esterification Esters are an incredibly important functional group in organic chemistry. Esters are typically very pleasant smelling molecules and are therefore frequently used in the fragrance industry and as flavoring ingredients. Some representative esters are shown in figure 1 below.

What is the percent yield of an ester?

The expected yield of the ester was 9.45 g; therefore, the percent yield of this reaction was 78.5%. When placed into the infrared spectrometer, the energy bands given off by the compound identified the sample as an ester. There are 3 unique spikes in the graph that indicate the presence of an ester.

What are the disadvantages of Fischer esterification?

In contrast, rapid reactions involving acid anhydrides or acid chlorides are often kinetically-controlled . The primary disadvantages of Fischer esterification routes are its thermodynamic reversibility and relatively slow reaction rates—often on the scale of several hours to years, depending on the reaction conditions.
