SWIM had heard RP is soluable in CS2, could it be possable that you dissolve the RP from matchboxes using CS2 and filtering out the impurties? then disilling off the CS2 leaving the RP behine.

Red phosphorus: Red to violet powder; polymorphism: Roth, DeWitt, Smith, J. Am. Chem. Sec. 69, 2881 (1947). Its properties are intermediate between those of the white and black forms. Sublimes at 416°, triple point 589.5° under 43.1 atm. d. 2.34. Insoluble in orgamc solvents. Soluble in phosphorus tribromide. Less active than the white form; reacts only at high temperatures. Yields the white modification when distilled at 290°. Catches fire when heated in air to about 260° and burns with formation of the pentoxide. Burns when heated in an atmosphere of chlorine.
White phosphorus: Colorless or yellowish, transparent, crystalline solid; darkens on exposure to light; m. 44.1° (vapor press. 0.181 mm.); b. 280° d. 1.83; volatile; sublimes in vacuo. at ordinary temperature when exposed to light. When exposed to air in the dark, emits a greenish light and gives off white fumes. Almost insoluble in water (one part in 300,000 parts of water); very slightly soluble in abs. alcohol (1 g./ 400 ml.); slightly sol. in abs. ether (1 g./ 102 ml.); soluble in chloroform (1 g./ 40 ml.); soluble in benzene (1 g./ 35 ml.); very soluble in carbon disulfide (1 g./ O.8 ml.). Solubility in oils: one gram phosphorus dissolves in 80 ml. olive oil, 60 ml. oil of turpentine, about 100 ml. almond oil.
Ignites at about 30° in moist air; the ignition temperature is higher when the air is dry.
