Red phosphorus reacts in the cold with SELENIUM OXYCHLORIDE evolving light and heat; white phosphorus reacts explosively [Mellor 10:906 1946-47]. When potassium is brought into contact with SELENIUM OXYCHLORIDE in the cold, an explosion occurs [Mellor 10:908 1946-47]. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291]. Powdered antimony ignites on contact with the chloride, [Mellor, 1947, Vol. 10, 906]. With metal oxides, i.e. silver oxide, light is evolved and heat sufficient to decompose the mixture, [Mellor, 1947, Vol. 10, 909].
