The invention discloses a method for preparing 2, 4, 6-trinitroresorein; firstly, resorcinol is dissolved in acetic acid with volume concentration of 5%-50%; by magnetic stirring, ammonium ceric nitrate water solution is added in and the obtained solution is heated to the temperature of 30-60 DEG C; the mol ratio of the reactants of resorcinol, ammonium ceric nitrate and water is 1:1.6:0.05-0.22,and the reaction lasts for 0.8-1.6h; when the reactants are fully converted into products (TLC tracking, ethyl acetate: ligarine=2:1), the stirring is stopped; the products are poured into ice water and brownish red solid matters are separated out; after suction filtration, distillation, water rinse and precipitation of 2-3 times, 2, 4, 6-trinitroresorein is obtained. The method of the invention adopts environmental-friendly chemical ammonium ceric nitrate as nitrating reagent, the operation is convenient, the reaction period is short and the production cost is reduced.
