Abstract The preparation of acetanilide is an organic chemistry experiment for the sophomore students in our university. The yields vary widely and are often low when the reactions are simply stopped on the basis of the reaction phenomenon or the reaction time when the conventional method is used. Hence, TLC monitoring is employed and the reaction is reproducible and the yields usually maintain high. The product is characterized by qualitative and quantitative analysis with internal standard by NMR and FT-IR spectroscopy.The students' motivation on the research is improved by the modification of the current experiment.The improved methods can be popularized in the undergraduate experiment.
