During this experiment, 1-propanol was reacted with propanoic acid using acidic conditions and the n-propyl propanoate was obtained in 25.98% yield. The product was light tan color with a pineapple mixed with acetone aroma. The sulfuric acid, the catalyst was used to speed up the reaction but did not affect the percent yield. The IR spectroscopy was analyzed and it showed that water was still present in my product since above the 3000 cm-1 there are large absorptions, indicating there are O-H containing impurities. The peak at around 1700 cm-1 is due to C=O stretching vibrations of a carbonyl C=O bond. The stretch from 2968.45 cm-1 to 2881.65 cm-1 illustrates the carbon and hydrogen bond. The two peaks around of range of 1000 cm-1 to 1200 cm-1 where 1188.15 cm-1 and 1083.99 cm-1 are located are due to C-O stretching vibrations of C-O bonds, thereby concluding the purity of ester.
