Verfahren zur Herstellung von passiviertem,rotem Phosphor

摘要

Production of passivated red phosphorus. Between about 10 and 85 weight percent powdered red phosphorus having a particle size of up to 100 microns is treated with between about 90 and 15 weight percent of molten epsilon -caprolactam, under inert gas; the resulting homogeneous and phosphorus-containing blend is cooled in a suitable cooler until solid; and solidified material in the form of lumps or scale is removed from the cooler.
