[0023] see Figure 1-2
[0024] Known by above technical scheme, 1, a kind of method for preparing 2,4-dichloroacetophenone comprises the following steps:
[0025] S1: Mix and stir dichlorobenzene, aluminum trichloride, and amide additives;
[0026] S2: When the stirring temperature rises to 40°C, add acetyl bromide dropwise to it for reaction, the dropwise addition process lasts for 2-3 hours and keep warm for 1-2 hours after the temperature is raised to 100°C, and when the temperature is lowered to 50°C, 2,4-dichloroacetophenone synthetic liquid;
[0027] S3: Add the 2,4-dichloroacetophenone synthesis liquid in step 2 to hydrochloric acid for acidolysis and layering, and separate the oil...
