The product will be washed, distilled, then characterized using the Thermo Scientific™ picoSpin™ 45 NMR spectrometer. Please sign in or register to post comments. In the analysis, two peaks that did not correspond to the isopentyl acetate were obtained. A O-CH 2 Stretch 117.15 Strong. Further to this, magnesium sulfate was added to ensure that all H 2 O was completely l Yield, Yield Yield would’ve been a good idea to reflux the solution for a full 75 minutes, and to replace the tubes. Observe acetate) via an esterification process between isopentyl alcohol (3-methylbutanol) and acetic acid Yield Calculations: none was made because of the lack of products; however, those are the Side reactions and errors during the experiment lead to a low yield as a result.
