Experiment 5: Synthesis of Esters: Fischer Esterification Using an Acetic Acid and an Unknown Alcohol Esther Lande Chem2211 L February 26, 2018 Introduction Esters are non-hydrocarbon organic compound that form reactions between an acid and an alcohol with the elimination of water. It is the product of esterification reaction. Fishre esterisficatipn is known to be most accurate and efficient process to synthesize ester because it is an equilibrium and it is reversible. Isobutyl acetate is found in fragrances, food additives, ink, toner, and colorant products, paints and coatings.1 Percent yield= Actual Yield . 70 grams ______________ X 100 =…show more content…
Discussion 1. After analyzing the IR Spectrum, 1H NMR, and 13C NMR of the reaction , the ester product was identified as the isobutyl acetate. The unknown alcohol given to me which was # 30 was identified as isobutanol. Through the Fischer Esterification of acetic acid and the unknown alcohol- isobutanol, we calculated the theoretical yield which was 1.80 g and the actual yield was 0.70 g. The percent yield was calculated by dividing the actual yield to the theoretical yield then multiply it by 100 which results to 38.8%. The percent yield calculated was a bit low. The low percent yield of the product might be caused by a loss of product occurred in the separation and purification of the production. The low of percent yield might be caused also by transferring the mixture from one conical vial to another and it might even be low because of some products that probably were not transferred totally to the vial from Hickman still apparatus.The IR
