Stabilized and desensitized flowable red phosphorus

Abstract From the Canadian patent

Stabilized and desensitized pulverulent flowable red phosphorus consisting of particles with a size of at most 2 mm, and process for making it. To this end red phosphorus, is prepared from yellow phosphorus. Next an aqueous suspen-, sion of pulverulent red phosphorus is freed from residual fractions of yellow phosphorus by treating it with a sodium hydroxide solution, and the red phosphorus in the aqueous suspension is stabilized with aluminum hydroxide and a hardened epoxide resin and desensitized in the aqueous suspension by means of a water-emulsifiable organic compound which is liquid, inactive with respect to phosphorus and has a low vapor pressure at room temperature and at …
