PROBLEM TO BE SOLVED: To provide a production method of RDX in which a content of HMX is made few, thereby fastening of a crystal of the HMX to an inner wall of a crystallization tank is made few, and secular change of impact sensitivity is made few.SOLUTION: A production method of RDX is configured such that a solution in which ammonium nitrate is dissolved in concentrated nitric acid, a solution in which hexamethylene tetramine is dissolved in acetic acid, and acetic acid anhydride are made a raw material, the raw material is performed by nitration, then added by water to be subjected to hydrolysis, subjected to filtration to separate waste acid, then subjected to water washing, next crude RDX obtained by performing wash boiling is dissolved by an organic solvent to perform crystallization, performed by water washing, then is filtered to perform recrystallization, and the production method of RDX is characterized in that a particle of 74-125 μm in the RDX subjected to crude crystallization and/or recrystallization is removed. |
