| description | The invention belongs to the technical field of chemical engineering, and particularly relates to a method for treating fluorine ions in m-aminotrifluorotoluene, which comprises the following steps: S1, pretreating biomass, and then mixing the treated biomass with fine lime of which the main component is calcium oxide to obtain a remover; s2, adding a remover into the m-aminotrifluorotoluene crude product in proportion, fully stirring and mixing the remover and the m-aminotrifluorotoluene crude product by using a mixing device, and adsorbing generated calcium fluoride precipitate by using biomass; s3, filtering the liquid in the mixing device, and separating the biomass and the calcium fluoride precipitate from the liquid; s4, drying the filtered filtrate, namely the m-aminobenzotrifluoride in which the fluorine ions are removed, so as to obtain refined m-aminobenzotrifluoride; according to the invention, biomass is utilized to adsorb calcium fluoride precipitate, the effect of subsequent single filtration is |
