It reduces sulfoxides to thioethers, even at " 78 �C . Meanwhile, heating a 1-iodobutane solution of PI 3 with red phosphorus causes reduction to P 2 I 4.
42.
Theories supported by laboratory experiments suppose that the color may be caused by complex organic molecules, red phosphorus, or yet another sulphur compound, but a consensus has yet to be reached.
43.
Red phosphorus is less reactive, does not ignite spontaneously, and its smoke does not cause thermal burns-for this reason it is safer to handle, but cannot be used so easily as an incendiary.
44.
In 1865, Johann Wilhelm Hittorf heated red phosphorus in a sealed tube at 530 �C . The upper part of the tube was kept at 444 �C . Brilliant opaque monoclinic, or rhombohedral, crystals sublime.
45.
Heating at ambient pressure to 250 �C or exposing to sunlight converts white phosphorus to red phosphorus where the P 4 tetrahedra are no longer isolated, but are connected by covalent bonds into polymer-like chains.
46.
P 4 O 6 is converted into the mixed P ( III ) P ( V ) species P 4 O 8 when heated in a sealed tube at 710 K, with the side product being red phosphorus.
47.
According to the affidavit, members of another right-wing fringe group called the Nevada Freedom Coalition helped Patterson get a mail-order shipment of four pounds of red phosphorus, a chemical that can be used to make both methamphetamine and explosives.
48.
The drug is easily made from codeine, iodine and red phosphorus, in a similar process to the manufacture of methamphetamine from pseudoephedrine, but desomorphine made this way is highly impure and contaminated with various toxic and corrosive byproducts . ).
49.
Or is red phosphorus much cheaper ? ( This is purely out of curiosity as I reduce an alcohol to a C-H bond for the umpteenth time on paper . . . ) talk ) 23 : 39, 7 November 2009 ( UTC)

Rarely, the impure reaction mixture from the hydrogen iodide / red phosphorus route is used without further modification, usually by injection; it is called " ox blood " . " Meth oil " refers to the crude methamphetamine base produced by several synthesis procedures.
