- Method for synthesizing 2-(5-fluoro-1, 5 dinitro-phenoxy) acetate
-
The invention discloses a method for synthesizing 2-(5-fluoro-1, 5 dinitro-phenoxy) acetate. 2, 4-dichloronitrobenzene serves as a raw material, nitration reaction is performed to obtain 2, 4-dichloro-1, 5-dinitrobenzene, the quantity of fluorinating agents and reaction conditions are controlled in aprotic polar solvents DMF, fluorination reaction with potassium fluoride is performed to obtain 2-fluoro-4-chloro-1, 5-dinitrobenzene, and the 2-fluoro-4-chloro-1, 5-dinitrobenzene is polarized in the etherified aprotic polar solvents DMF and subjected to etherification reaction with hydroxy acetate under the action of acid-binding agents and catalysts to obtain the 2-(5-fluoro-1, 5 dinitro-phenoxy) acetate. In addition, raw materials are inexpensive and easy to obtain, operation is simple andconvenient, technological conditions of reaction in all steps are mild, the method is high in safety and short in reaction time, and industrial production can be popularized.
