PROCESS FOR PRODUCING RED PHOSPHORUS Russian patent published in 1995 - IPC

Abstract RU 2032614 C1

FIELD: inorganic chemistry. SUBSTANCE: a solution of nonsymmetrical block copolymers and/or multihydrid alcohol and fatty acid esters in water is poured together with a solution of white phosphorus in hexane. The phosphorus to block copoly mers weight ratio is 1:(0.005-0.01). The water to hexane volumetric ratio is 1:1. The mixture is stirred till a multipurpose emulsion is formed and irradiated with ionizing radiation to a absorbed doze value of 0.5 to 2.0 mg. The resulting polymer is separated, washed and dried. EFFECT: improved process for producing red phosphorus. 2 cl, 2 tbl
