    Abstract: STABILIZED RED PHOSPHORUS The invention provides stabilized pulverulent red phosphorus comprising a homogeneous blend of red phosphorus particles with a size of at most about 2 mm, aluminum hydroxide and a further metal hydroxide as oxidation stabilizers, wherein the metal hydroxide is lead hydroxide. The homogeneous blend contains aluminum hydroxide and lead hydroxide in a total proportion of about 0.1 to 6 weight%, based on the quantity of red phosphorus, the aluminum hydroxide and lead hydroxide, calculated as Al2O3 to PbO, being used in a quantitative ratio of about 0.5 to 2.0.

    Abstract: 1518665 Stabilized red phosphorus HOECHST AG 2 May 1977 [19 May 1976] 18259/77 Heading C1A [Also in Division C2] Stabilized phosphorus comprises a homogeneous blend of red phosphorus particles of size at most 2 mm with the Al, Mg, Ca or Zn salt of the orthophosphoric acid mono- or di-ester of lauryl alcohol tetraethyleneglycol ether, stearyl alcohol, or phenol hexaethyleneglycol ether or a mixture thereof, the salt being present in amount 0À25-5% by weight. The composition may be prepared by heating a suspension of the P and the ester(s) in water to 60‹-95‹ and adding an aqueous solution of a water-soluble salt of Al, Mg, Ca or Zn, filtering and drying.
