发明名称 METHOD FOR PRODUCTION OF AMORPHOUS RED PHOSPHOROUS
摘要 FIELD: chemical technology. SUBSTANCE: amorphous red phosphorous is prepared by polymerization of white phosphorous. Said process is carried out in dispersion medium in the presence of high molecular weight oxygen-containing emulsifier, treatment with ionizing irradiation being used. Said treatment is carried out till absorbed dose is 0.5-1.5 MGa, it is followed by separation of non-reacted white phosphorous with the help of selective extraction and by drying of desired product. Mixture of white phosphorous with additive being chosen of graphite, TiO, Al(OH), Mg(OH)is used for mentioned above polymerization, quantity of said additives being 0.5-5 mass %. Mixture of water with organic solvents being chosen of benzene, CCl, CHCl, decane at their ratio 1:1-2 respectively is used as mentioned above dispersion medium. Particles of thus prepared red phosphorous have average size 2-15 μm. EFFECT: improves efficiency of the method.
