N-propyl propanoate (n-propyl propionate) was synthesized using propanoic acid and 1-propanol in the presence of sulfuric acid, resulting in a 62.5 % yield. The initial odor of the mixture of propanoic acid and 1-propanol was very unpleasant and strong. After the reaction was complete, the odor was like that of rubbing alcohol (Table 1). IR spectroscopy was used to determine the purity and identity of the product. The IR spectroscopy revealed the presence of an ester, which correlates to the strong, sharp peak at around 1741 cm-1. In addition, the peak at 2968 cm-1 indicates the presence of the C=O bond commonly found in esters. Lastly, there was a broad peak at 3550 cm-1, which indicates the presence of -OH groups. Because of the presence of alcohol impurities, this suggests that some of the reagents had not undergone the reaction.
Comments
good
Very good flow of words and work. Good job of explaining what each thing you found means, you dont just state the observation, you talk about the significance and what it means.
Your paragraph flowed very
Your paragraph flowed very well, you gave substantial details without being too wordy or exessive and transitioned between different topics smoothly.
Perhaps your last sentence
Perhaps your last sentence could elaborate on what part of the experiment might have contributed to the alcohol impurities found in the resulting compound.
