	Phosphorus - LoveToKnow 1911
		The crude phosphorus is purified by melting under water and then filtering through animal fl and afterwards through chamois leather, or by treating it, when molten, with chromic acid or a mixture of potassium bichromate and sulphuric acid; this causes the impurities to rise to the surface as a scum which can be skimmed off.
		Phosphorus trichloride or phosphorous chloride, PC13, discovered by Gay-Lussac and Thenard in 1808, is obtained by passing a slow current of chlorine over heated red phosphorus or through a solution of ordinary phosphorus in carbon disulphide (purifying in the latter case by fractional distillation).
		The phosphorus used in the British pharma copoeia is obtained from calcium phosphate, and is a waxlike non-metallic substance soluble in oils and luminous in the dark.
