Abstract
The acetylation technology of 2,4-dichlorofluorobenzene to manufacture 2,4-dichloro-5-fluoroacetophenone has been studied. Analyzing the effects of operation conditions on the conversion ratio and etc., the optimum reaction conditions are obtained as follows: n(2,4-dichlorofluorobenzene)∶n(acetyl chloride)∶n(aluminum trichloride)=1∶2.0∶2.5, reaction time is 1.5h under 110℃ and another 1h under 120℃. Under the above-mentioned conditions the yield can reach 80.1%.
