In this experiment, carbolic acid was used as raw material, and the target product was obtained by the combination of acetylphenylamine, frying rearrangement, oximation and Beckmann rearrangement. Under the optimum reaction temperature and time, acetone was used as catalyst, and the total yield was 40.5%.
The second paragraph is translated as follows
The influence of different yields on the results of stir-frying rearrangement was discussed by equal rank operation experiment, and the influence of reaction conditions on the yield of target results in Beckmann rearrangement was studied, and the technological conditions were optimized. Finally, the structure of the main products was identified by melting point measuring instrument and infrared spectrometer.
