Aliphatic Amine Experiment
Discussion
An amount of 853 mg of alcohol was obtained in the flask. After the experiment was performed, amount recovered was 1259mg (I think you have these flipped). Percent yield of the crude product was 67.75%. (What does this percentage mean?) The IR spectrum of purified product identified the Arene strand of 2969.71 indicating C-H stretch. Ester which indicated a C=O stretch of a 1750-1735. Aliphatic amines showed an absorption band of 1217.62 indicating a C-N stretch. (This makes no sense, look at the molecule you have and relate the points. Furthermore, you need to compare your results to a literature source)
An example of a practical application would be using the ester to produce flavors in products. It could be used in a laboratory where they are trying to find out the best taste to use in a given product. (This needs more detail) …show more content…
The first improvement would be to have a heating instrument that heats to a desired point and does not go above or below a set temperature. Another improvement would be using different glass ware or heating supplies when boiling water in order to shorten the boiling time (This is not a valid improvement). The final improvement to this protocol would be using more accurate supply to remove the aqueous layer from the bottom of the conical vial, without taking the upper layer (This is not a valid improvement).
Conclusion
The overall process of synthesizing ester by esterification of a carboxylic acid with an alcohol was accomplished, the percent recovery, and IR results were
