The invention discloses a production technology of 3,5-dichloro-4-(1,1,2,2-tetrafluoroethoxy)benzenamine, and relates to the technical field of chemical product production. 2,6-dichlorophenol and nitric acid are mixed to be subjected to a nitration reaction, and 2,6-dichloro-4-nitrophenol (DCNP) is obtained; the 2,6-dichloro-4-nitrophenol (DCNP) is subjected to a reduction reaction in hydrogen, and 4-amino-2,6-dichlorophenol (DCAP) is obtained; then, the 4-amino-2,6-dichlorophenol (DCAP) and tetrafluoroethylene are subjected to an addition reaction, and 3,5-dichloro-4-(1,1,2,2-tetrafluoroethoxy)benzenamine is obtained. The reaction purpose is strong, few by-products are produced, the conversion rate is high, and postprocessing is easy.
