Magnesium Phosphide

Magnesium phosphide is a dark gray crystalline solid. It is used in the form of pellets, which are charged with a suitable solvent to release the highly toxic and flammable phosphine gas.

Properties. Mg3P2 is stable at ambient conditions in dry air, but may ignite when it comes in contact with water or moist air (due to hydrolysis), since phosphine (PH3) is a highly flammable and toxic gas. Upon heating, magnesium phosphide decomposes slowly to magnesium oxide (MgO) and phosphorus pentoxide (P2O5).

Synthesis. Magnesium phosphide can be prepared by reacting magnesium metal with phosphorus at approximately 400°C:

2 Mg + P4 → 2 Mg3P2

It can also be prepared by reacting Mg-halides (such as MgCl2) with calcium phosphide (Ca3P2):

MgCl2 + Ca3P2 → Mg3P2 + CaCl2

Use. The main use for magnesium phosphide is as a rodenticide. The main advantage of this compound over aluminium phosphide as a rodenticide is that the latter can explode due to moisture on its surface, while

Magnesium phosphide is a chemical compound with the formula Mg3P2. It is a light brown powder. It ignites in air and burns with an intense purple flame, producing phosphorus pentoxide and magnesium oxide. The density of the solid is 2.94 g/cm3. The CAS number of magnesium phosphide is 12057-74-8.

Magnesium phosphide can be used as a rodenticide against rats and mice, since rodents are known to have a natural craving for phosphorus, which they seek when their bodies lack it.[4]

The mechanism by which magnesium phosphide acts as a rodenticide involves the production of the gas phosphine (PH3) in the acidic conditions of the stomach.[4] The toxicity of PH3 to mammals is low (the LD50 in mice is 7,000 ppm),[5] but in insects, it causes rapid cellular respiration dysfunction by irreversibly binding to mitochondrial cytochrome oxidase.[6][7]

Magnesium phosphide is a chemical compound. The molecular formula of this chemical is Mg3P2. The IUPAC name of this chemical is magnesium phosphide. With the CAS registry number 12057-74-8, it is also named as Trimagnesium diphosphide.

Properties of magnesium phosphide (1) :

Light gray powder or dark gray crystals. It decomposes in water to give phosphine. It is freely soluble in dilute acids and alkalis and insoluble in alcohol, benzene, ether and petroleum ether.

Phosphide, any of a class of chemical compounds in which phosphorus combines with a metal. Most phosphides are binary compounds (those containing two different elements), the most important of which are those of sodium, calcium, and zinc. Phosphides are frequently used as high-energy fuels in rockets and torpedoes.

The phosphides Mg3P2 (magnesium phosphide), Ca3P2 (calcium phosphide), and Zn3P2 (zinc phosphide) all react with water to produce phosphine, PH3. This reaction is used in the commercial production of phosphine by the direct reaction of magnesium phosphide with water:

Mg3P2 + 6H2O → 3Mg(OH)2 + 2PH3

In this reaction the amount of energy released is sufficient to cause ignition of the hydrogen gas produced that results in an explosion. Ca3P2 and Zn3P2 also react explosively with water, but they are less commonly used than Mg3P2 because they are more expensive to produce. Magnesium phosphide was first developed in the early 1900s by A.I. Shchukarev at the Lomonosov Institute in Moscow for use as a rocket propell

Magnesium phosphide is a highly toxic inorganic compound with the formula Mg3P2. It is used in pest control and as a dopant in semiconductors. The principal hazards from this salt are from the toxic phosphorus and flammable magnesium.

Magnesium phosphide is a chemical compound. Its molecular formula is Mg3P2, and its molar mass is 123.94 g/mol. It contains magnesium and phosphorus. The chemical is used as a pesticide to kill small invertebrates, especially moles and gophers.

It can be used in rodent baits and pheromone lures to kill small animals such as moles, voles and gophers.[1] Magnesium phosphide is sold under various names including Talunex, Talunex P, Magtoxin, Magtoxin-CMC, Magtoxin-HPC, Talunex Gopher Bait, Talunex Mole Bait, Fumitoxin A-5559, Phostoxin and Weevil-Cide RTU.[2][3][4]

Magnesium phosphide generates phosphine (PH3) gas upon contact with moisture or acids.[2] PH3 is toxic to humans with an exposure time dependent LD50 of about 0.1 mg/kg.[5]

These reagents are produced by the reaction of phosphine (PH3) with magnesium metal. The process is carried out in an inert (dry) atmosphere and can be conducted under anhydrous conditions; however, the product usually contains small amounts of water. Typically, the product contains ~3% H2O and 18-25% P2H4 in Mg3P2. The reagents are shipped as a dry powder or as pellets. They react with moisture to generate phosphine (PH3). The phosphine is toxic and flammable and special care should be taken during storage and handling.

Magnesium phosphide is the inorganic compound with the formula Mg3P2. It is probably the most commonly encountered phosphate of magnesium. It is a dark-brown crystalline solid that finds some use as a rodenticide and insecticide.

Applications

Magnesium phosphide, Mg3P2, occurs in nature as a rare mineral called hillebrandite. Synthetic Mg3P2 is commercially available, usually in pellet form. Like many other phosphides, it reacts with water or acid to give phosphine, PH3. The reaction with water produces hydrogen gas and heat:

Mg3P2 + 6H 2O → 3Mg(OH)2 + 2PH3 + 3H2

If heated under controlled conditions, magnesium phosphide converts to phosphorus triiodide and magnesium iodide.[5]

Magnesium phosphide is a chemical compound. Its chemical formula is Mg3P2. It contains magnesium and phosphate ions. It is a solid at room temperature.

The phosphate rock reacts with sulfuric acid to produce a slurry of calcium sulfate and phosphoric acid. The phosphoric acid is purified by removal of impurities such as silicon, aluminum, iron, and magnesium by precipitation with lime. The resulting phosphoric acid may be used in the production of fertilizer, or it may be reacted with ammonia to form ammonium phosphate fertilizers.
