Objective
The purpose of this experiment is to determine the results of a reaction of Acetic Anhydride and Heptylamine, using HNMR to analyze the results.

Results
Time: 20 minutes [|CRSEXP042A-NMR1] pure acetic anhydride [|CRSEXP042B-NMR1] pure heptylamine [|CRSEXP042C-NMR1] half by volume acetic anhydride and half by volume heptylamine [|CRSEXP042D-NMR1] one drop acetic anhydride in excess heptylamine [|CRSEXP042E-NMR1] one drop heptylamine in excess acetic anhydride

Time: 19 hours [|CRSEXP042A-NMR2] pure acetic anhydride [|CRSEXP042B-NMR2] pure heptylamine [|CRSEXP042C-NMR2] half by volume acetic anhydride and half by volume heptylamine [|CRSEXP042D-NMR2] one drop acetic anhydride in excess heptylamine [|CRSEXP042E-NMR2] one drop heptylamine in excess acetic anhydride

Discussion
The reaction between acetic anhydride and heptylamine occurs very rapidly, even without a catalyst. The HNMR spectra at 20 minutes and 19 hours look identical, which proves that the reaction is complete within 20 minutes. When mixing the reagents, heat and white gas were immediately produced. Based on literature searches, this reaction is not performed very often. performed the reaction to determine whether the product, N-heptyl acetamide, would be a useful insecticide and/or acaricide. The reactions they performed were under suitable conditions. As proven by the experiment, this reaction does not require a catalyst because it reacts very rapidly when the reagents are simply mixed.
