Single-Step Synthesis of Secondary Phosphine Oxides.
Phosphine oxide is reported as an intermediate in the room-temperature polymerization of phosphine and nitric oxide to solid PxHy. Phosphine oxide is also stable in a water-ethanol solution by electrochemical oxidation of white phosphorus and it slowly disproportionates into phosphine and hypophosphorous acid.
Phosphine is also used as an intermediate in the synthesis of flame retardants for cotton fabrics, as a doping agent for n-type semiconductors, a polymerization initiator, and a condensation catalyst. (1,3) Sources and Potential Exposure Occupational exposure to phosphine may occur during its manufacture or use. (1-3) The general public may be exposed via the inhalation of contaminated ambient.
Phosphine (PH 3), also called hydrogen phosphide, a colourless, flammable, extremely toxic gas with a disagreeable garliclike odour.Phosphine is formed by the action of a strong base or hot water on white phosphorus or by the reaction of water with calcium phosphide (Ca 3 P 2).Phosphine is structurally similar to ammonia (NH 3), but phosphine is a much poorer solvent than ammonia and is much.
Phosphine definition is - any of various derivatives of phosphine analogous to amines but weaker as bases.
Phosphine. Contents - Previous - Next. Phosphine or hydrogen phosphide (PH 3) is a low molecular weight, low boiling point compound that diffuses rapidly and penetrates deeply into materials, such as large bulks of grain or tightly packed materials.The gas is produced from formulations of metallic phosphides (usually aluminium or magnesium phosphide) that contain additional materials for.
Phosphine oxide definition is - any of a series of oxides having the general formula R3PO that are obtained by oxidation of trisubstituted phosphines.
The essence of high-temperature colloidal synthesis is to use high-boiling tri-n-octylphosphine oxide (TOPO), which simultaneously acts as solvent, metal precursor and anticoagulant forming the ligand shell of CQDs. Tri-n-octylphosphine (TOP), which is structurally isomorphic to TOPO, acts as nonmetal precursor and also participates in the formation of the ligand shell of CQDs.
