2010-09-16 Experiment 19: Fischer Esterification‚ Conclusion The objective in this experiment was to efficiently perform an Fischer esterification of 1-butanol and acetic acid to form water and n-butyl acetate‚ and to confirm the esterification using IR spectroscopy analysis. It was found that 0.734 grams of n-butyl acetate was formed with a percent yield of 61%. The product was confirmed using IR spectroscopy and boiling point confirmation. The reaction mechanism for this specific reaction was as follows:

Introduction In this lab‚ caproic acid was synthesized in a multi-step process that involved the synthesis of three intermediates – diethyl n-butylmalonate‚ potassium n-butylmalonate‚ and n-butyl malonic acid respectively. An IR was used to characterize the starting material‚ n-bromobutane‚ and the first intermediate‚ diethyl n-butylmalonate; while IR and NMR were used to characterize the final product‚ caproic acid. Reactions‚ Mechanism and Theory Caproic acid a.k.a n-hexanoic acid is a carboxylic

How Carboxylic Acids and Alcohols React to Produce Esters: Esters and Ester Production: Esters are abundant and ever present‚ and are the chemical basis of almost all fatty acids and oils. Small esters are responsible for the aroma of fruits‚ perfumes and‚ by extension‚ wines and other alcohols. Esters are formed when a carboxylic acid and an alcohol chemically combine‚ losing a molecule of water in the process. Carboxylic acids are organic molecular compounds that form a homologous series

mechanism for the acid-catalyzed hydrolysis of methyl benzoate. Introduction: The ester group is an important functional group that can be synthesized in a number of different ways. The low-molecular-weight esters have very pleasant odors and indeed are the major components of the flavor and odor aspects of a number of fruits. Although the natural flavor may contain nearly a hundred different compounds‚ single esters approximate the natural odors and are often used in the food industry for artificial
