A PROCESS FOR PREPARATION OF FINE ß-HMX BY ANTISOLVENT PRECIPITATION

摘要

The present disclosure relates to a process for preparation of fine ß-HMX of size less than 5µm, the process comprising: dissolving ß-HMX in an organic solvent at a temperature ranging from 300C-450C to obtain a saturated solution; adding an organic anti-solvent to the saturated solution at ambient temperature to obtain a precipitated ß-HMX; and drying the precipitated ß-HMX at a temperature ranging from 500C-700C for 10-12 hours to obtain fine ß-HMX with size less than 5µm, wherein, the solvent to anti-solvent ratio is of range 1:100 to 1:10.
