No relevant data found. ♦Yellow phosphorus: t ½ (pH 7)=280h at 0 °C [6] t ½ (pH 7)=268h at 3 °C [6] t ½ (pH 7)=11.9h at 93 °C [6] No relevant data found &RQFOXVLRQ +HDOWK Red phosphorus is often contaminated with white and yellow phosphorus. Therefore information of the two other allotropic forms included. Red phosphorus is not absorbed very well. Lethal dose in mammals 1.4 - 4.8 mg/kg bw (allotropic form not specified). Pure red phosphorus is apparently less harmful than the two other allotropic forms. Inhalation of 4.3 mg/l red phosphorus (1h) or 1.5 mg/l (4 h) killed 9 respectively 2 of 10 rats. The substance is classified as highly flammable and may explode when exposed to heat or by chemical reaction with oxidisers. Red phosphorus can also react with reducing materials and represent a moderate explosion hazard by chemical reaction or on contact with organic materials. It reacts with oxygen and water vapour to produce the toxic phosphine. The abiotic degradation of yellow phosphorus proceeds at ambient temperature. (QYLURQPHQW No ecotoxicological data on red phosphorus were located. Yellow phosphorus is very toxic to crustaceans and fish in standard tests (down to 0.011 mg/l and 0.018 mg/l, respectively) 5HIHUHQFHV 1 Chemfinder: http://www.chemfinder.com/cgi-win/cfserver.exe/ 2 HAWLEY’S CONDENSED CHEMICAL DICTIONARY.
