摘要(英):
The invention discloses a method for preparing 2-bromo-5-fluorobenzotrifluoride. In the method, fluorobenzotrifluoride is used as a raw material, bromine is used as a brominating agent, and the 2-bromo-5-fluorobenzotrifluoride is synthesized in the presence of sulfuric acid and a composite catalyst at normal temperature. By means of the method, the yield reaches 90.0% or above, the purity reaches 99.0% or above, the raw materials used in the reaction process are convenient to purchase, the production cost is low, the waste acid obtained in the reaction process can be recycled, the post-treatment is easy, the reaction conditions are mild, and the method has good economic benefits and social benefits.
