A method of adjusting the yield of a manufactured compound comprising primarily two energetic materials to yield a product comprising primarily one of the two energetic materials. Specifically, embodiments of the present invention provide a method of purifying a compound primarily comprising RDX and HMX to achieve a desired purity of RDX with an acceptable yield percentage. By adding sufficient acetonitrile (ACN) to the manufactured compound to dissolve it and form a solution; adding a pre-specified volume of water to the resultant solution and stirring sufficiently to precipitate at least the RDX; separating and drying the precipitate, a pre-specified purity and yield percentage of RDX may be obtained by varying the volume of water added. The process uses relatively environmentally benign recyclable solvents at ambient temperature and pressure reducing both environmental impact and energy costs.
