Qualitative and Quantitative Analysis of Esterification Reaction Using a Micro NMR Spectrometer

45 MHz benchtop NMR spectrometer was applied to the basic organic experiment teaching.Ethyl acetate was synthesized from acetic acid and ethanol.The structural and quantitative analysis of the product was carried out on the micro-nuclear magnetic resonance spectrometer.In the experimental class,the synthesized product can be used for structural characterization and quantitative analysis immediately,so the spectral theory and experiment combined perfectly.Practice shows that the experiment improves the confidence of students in the operation of NMR instruments,reducing the fear of students on NMR instruments.
