Benzene, Fluoro-; Mono Fluoro Benzene; _|_; Benzene Derivative
Brief Introduction
Fluorobenzene is a colorless liquid with a similar odor to benzene. It is soluble in ether and alcohol but insoluble in water. The product is mainly used for the preparation of the main raw materials of the antipsychotic drugs, such as fluguabutanol, daloglabenzene, trifluoroperidobenzene, pentafluorolidol, etc. At the same time, it can also be used for the identification of pesticides, egg killers, plastics and resin polymers. Fluorobenzene and γ- Chlorobutyryl chloride can be prepared by condensation γ- Chloro-p-fluorophenone, is the most commonly used drug in butyrylbenzene antipsychotics.
