RDX PREPARATION METHOD FOR SUBMICRON AND MICRON SIZE- SPHERICAL RDX PARTICLES

摘要

The present invention relates to a method for preparing spherical RDX (Cyclotrimethylene trinitramine) particles of submicron and micron size, and more particularly, to a method for preparing RDX solution by dissolving RDX in an organic solvent. Mixing the RDX solution and an anti-solvent to precipitate RDX particles; And mixing the RDX solution or the semi-solvent with a surfactant before mixing the RDX solution and the semi-solvent. According to the present invention, spherical RDX particles having submicron size and micron size can be produced with high productivity as compared with conventional methods. Such spherical RDX particles have the advantages of maximizing the explosion pressure as the packing density increases, RDX particles can be produced. Since they exhibit a rapid energy release rate due to their fine particle size, they can be widely used as civil and military compositions such as high-explosives and solid composite propellants.
