The invention relates to a preparation method of aminodiphenyl ether, in particular to a method for preparing aminodiphenyl ether by p-nitrchlorobenzene serving as a raw material. The method includesthe steps: etherification reaction; oil-water phase separation of etherification products; catalytic hydrogenation reaction; filtering; rectification and the like. The method for preparing the aminodiphenyl ether by the p-nitrchlorobenzene serving as the raw material is clean, environmentally friendly, simple to operate, low in energy consumption and pollution-free in environment, and the aminodiphenyl ether prepared by the method is high in yield and purity. According to the method for preparing the aminodiphenyl ether by the p-nitrchlorobenzene serving as the raw material, phase transfer catalysts are less in dosage, and fewer by-products are generated in the reaction process.
