    Abstract: STABILIZED RED PHOSPHORUS AND PROCESS FOR MAKING IT Production of stabilized pulverulent red phosphorus. The phosphorus so stabilized comprises a homogeneous blend of red phosphorus particles with a size of at most about 2 mm and a metal compound of the second or third group of the Periodic System as an oxidation stabilizer, wherein the metal compound is the aluminum, calcium or zinc salt of a phosphinic acid of the general formula in which R1 and R2 each stand for an alkyl, cycloalkyl, aryl or aralkyl group having 1 to 20 carbon atoms, the metal compound being present in the homogeneous blend in a proportion of about 0.5 to 5 weight %.

    Abstract: 1519929 Red phosphorus HOECHST AG 27 May 1977 [17 July 1976] 22500/77 Heading C1A Stabilized pulverulent red phosphorus comprises a homogeneous blend of red phosphorus particles with a size of at most about 2mm and as an oxidation stabilizer a metal compound of the second or third group of the Periodic System, the metal compound being the aluminium, magnesium, calcium or zinc salt of an alkyl-, cycloalkyl-, aryl- or aralkyl-phosphonic acid having 1 to 20 carbon atoms, the metal compound being present in the homogeneous blend in a proportion of 0À5 to 5 weight per cent. Red phosphorus particles may-be intimately blended with 0À5 to 5 weight per cent, based on red phosphorus, of an alkyl-, cycloalkyl-, aryl- or aralkyl-phosphonic acid having 1 to 20 carbon atoms; the blend suspended in water and the suspension heated to 60 to 95‹ C.; the suspension gradually admixed with at least stoichiometric proportions of an aqueous solution of a water-soluble aluminium, magnesium, calcium or zinc salt to cause precipitation of the respective phosphoric acid salt from the aqueous suspension at a pH of 3À0 to 6À0 and preferably at a temperature of from 80 to 90‹ C.; the resulting mixture filtered, and the filter residue dried at elevated temperature, suitably at 80 to 130‹ C., and if desired, under reduced pressure. Preferred water-soluble salts are Al 2 (SO 4 ) 3 .18H 2 O, Ca(NO 3 ) 2 .4H 2 O, ZnSO 4 .7H 2 O and MgSO 4 .7H 2 O, which may be used in the form of 5 to 20 weight per cent aqueous solutions. The aluminium salt is suitably precipitated at pH 3À0 to 3À5 and the salts of the other metals at pH 5À0 to 6À0.

    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.
