METHOD OF MODIFYING SURFACE OF HEXANITROHEXAAZA-ISOWURTZITANE PARTICLES Russian patent published in 2010 - IPC C06B25/34 C06B45/22 

FIELD: chemistry.

SUBSTANCE: invention pertains to explosives. The invention discloses a method of modifying the surface of hexanitrohexaaza-isowurtzitane (CL-20) particles. Hexanitrohexaaza-isowurtzitane particles are added to water in mass ratio of 1:100 and stirred for 5-10 minutes. The obtained suspension is mixed with a suspension of trans-1,4,5,8-tetranitroso-1,4,5,8-tetraazadecalin in water for 10-20 minutes. A 1% aqueous solution of nonionic praestol solution is added while stirring continuously for 30±10 minutes. The mixture is cooled with water to 5-10°C, filtered and dried at 50-70°C to constant weight.

EFFECT: invention reduces the hazard of the process of applying the modifying coating onto the surface of crystals highly sensitive to mechanical effect of CL-20.
