Red phosphorus

Red phosphorus has shades from purple-red to purple, and in the cast condition — dark purple with copper shade has a metallic luster. Reactivity of red phosphorus is much lower than the white; he inherent to this extremely low solubility. Dissolving red phosphorus possible only in some molten metals (lead and bismuth), sometimes used for large it crystals.

Red phosphorus is a polymer with a complex structure. The reagent is prepared by polymerization of phosphorus yellow. The result forms a substance of red-brown color. Red phosphorus is well soluble in methanol, insoluble in water and diethyl ether, almost soluble in methylamine.

Phosphorus is the most important nutrient element and at the same time finds a wide range of application in the industry. Red phosphorus used in the manufacture of matches. It with finely ground glass and adhesive is applied on the lateral surface box. By friction of the match head, consisting of potassium chlorate and sulfur, ignition occurs.

The substance is extremely toxic, the fire, ignited by friction or impact. When working with red phosphorus be sure to use personal protective equipment, including gas mask or respirator and protective clothing.

The substance has a lower toxic than white phosphorus, so it can be used in production.

Store the reagent should a sealed container, open container you should use the special tool avoid shock or friction.
