METHOD OF RECOVERING OCTAGON FROM ACTIVE BINDER-BASED MIXED SOLID ROCKET FUELS

摘要

FIELD: armament disposal.;SUBSTANCE: invention provides a method for recovering octogene from charge of nitroglycerol-based mixed solid rocket fuel comprising: water-jet destruction of the charge to form suspension of oxidant aqueous solution and polymer matrix particles filled with dispersed octogen and plasticized nitroglycerol; removing oxidant aqueous solution from the suspension to form concentrate of polymer matrix material; suspending and neutralizing resulting concentrate in alkali aqueous solution; separating precipitated octogen from suspension; separating and washing solid phase; separating solid phase into fractions with densities ρ ~1.2, 1.2 ρ1.8, ρ ~1.8 g/cm³ or higher; reusing fraction ρ ~1.2 g/cm³ as polymer waste; extracting octogene from fraction with density 1.2 ρ1.8 using organic solvent; combining precipitated octogene, octogen fraction with density ρ ~1.8 g/cm³ or higher; and extracting octogene as recovered.;EFFECT: enabled save recovery process.;4 cl, 1 dwg, 1 tbl
