Method for synthetizing 3,5-dichloroaniline

The invention discloses a method for synthetizing 3,5-dichloroaniline by using industrial production residues, namely meta-position oil, of p-nitrchlorobenzene and ortho-nitrochlorobenzene by two steps of chlorination and reductive dechlorination. The method adopts the following technical scheme: adding an organic solvent to nitrochlorobenzene meta-position oil as a raw material, directly producing a quintozene mixture by one-step chlorination under the effect of a catalyst, reacting for 0.5-10 hours under the condition of 10-180 DEG C, and then cooling to 30 DEG C; filtering out quintozene, and putting into an autoclave after washing into a neutral state by hot water; carrying out dechlorination reduction reaction under the effects of an organic solvent and the catalyst, wherein the reaction temperature is 60-200 DEG C, the reaction pressure is 1-20 MPa, and the reaction time is 1-20 hours; cooling to room temperature after the reaction is ended; leading in oxygen or air to stir after blowing off; filtering and distilling under reduced pressure to remove the solvent, so as to obtain the product 3,5-dichloroaniline, wherein the yield is 80-90%. Waste materials are changed into precious materials by a synthetic route adopted by the technology disclosed by the invention; the target of zero emission is achieved; the method has the advantages of sustainable development, energy conservation and consumption reduction, and small environmental pollution.
