FIELD: chemistry, explosives.
SUBSTANCE: method of obtaining ultra fine hexanitrostilbene is proposed. Hexanitrostilbene is dissolved at temperature of 50-80°C in dimethylformamide. The hexanitrostilbene is precipitated by adding the obtained solution to a water solution of acid at 5-30°C, with agitation of by compressed air and volume ratio of the water solution of acid to the volume of hexanitrostilbene solution of 4-5. After separation by filtering, the residue is washed in distilled water, and then in a 15-25% water solution of acetone and is then dried in a vacuum.
EFFECT: obtaining ultra fine hexanitrostilbene with particle size less than 1 mcm.
