The invention belongs to the field of chemical technologies, and particularly relates to a synthesis method of 2,4-dichloro-5-fluorin(trichloromethyl)benzene. According to the method, 2,4-dichlor fluorbenzene and CCl4 are used as starting materials, under the action of ionic liquid 1,2-bis(N-methylimidazolium)ethane chlorine aluminate([C2mim][Cl2]-AlCl3), the 2,4-dichloro-5-fluorin(trichloromethyl)benzene is generated through reaction. The method has the advantages that the ionic liquid catalyst [C2mim][Cl2]-AlCl3) can be conveniently recovered and reused, the yield is high, and the proportionof a bipolymer by-product is reduced; by means of the method, the problem of using lots of alchlor as trichlorine methylation is solved, by using the ionic liquid, the usage amount of the CCl4 is reduced, and meanwhile, due to no post-reaction treatment, lots of acid water is avoided.
