Information

Red phosphorus is one of the allotropic forms of elemental phosphorus. It is an amorphous substance, reddish in color, slightly soluble in water and common organic solvents. Unlike white phosphorus, it is not soluble in carbon disulfide and non-toxic.
In contact with oxidizing substances, it changes, with a very violent and sometimes explosive reaction, to phosphorus pentoxide, producing a white smoke.

Red phosphorus is formed from white phosphorus at 250-270 °C or by strong irradiation with light. By heating under inert conditions, for example under a layer of oil, it can be converted back into white phosphorus. Although it is the most industrially produced form of phosphorus, little is known about its molecular structure. It is likely a polymer with partially layered structures similar to those in Hittorf's phosphorus, where all phosphorus atoms are bonded to three other atoms of the same element.

In chemistry, phosphorus is used as a reducing agent in some reactions. For example, in the presence of traces of iodine as a catalyst, it is able to reduce chlorosulfonates to mercaptans. It is also an important starting compound for the synthesis of various compounds of this element, from phosphorus trichloride, phosphorus pentachloride to then phosphines, etc.

It is also used in matches, in rubber induction and in fertilizer production
