The invention provides a high-quality single-compound explosive recrystallization method. A synthesized DNTF crude product is taken as a raw material, and is recrystallized in the presence of an organic solvent to prepare high-quality DNTF by adopting a solvent-nonsolvent method. The method comprises the following steps: dissolving DNTF in the organic solvent under the condition that reaction temperature is 50 to 60 DEG C, wherein the mass ratio of the organic solvent and the DNTF crude product is 2:1, adding 0.5 percent of a shape control agent after the DNTF is completely dissolved, and mechanically stirring for 30 min at the stirring speed of 2,000 r/m; adding nonsolvent deionized water to enable the solution to be oversaturated and separate out DNTF crystals for a certain time, vacuumizing, filtering and drying to obtain high-quality DNTF. According to the method, the defects of high mechanical sensitivity and poor formability of a background technology in a recrystallization process are overcome.
