Beschreibung

Barium peroxide, is a grayish-white powder that is slightly soluble in water. Barium peroxide is a dangerous fire and explosion risk in contact with organic materials and decomposes around 1450°F (787°C). It is also toxic by ingestion, is a skin irritant, and should be kept cool and dry in storage. The four-digit UN identification number is 1449. The primary uses of barium peroxide are in bleaching, in thermal welding of aluminum, as an oxidizing agent, and in the dyeing of textiles.

Chemische Eigenschaften

Barium peroxide is a grayish-white powder.

Physikalische Eigenschaften

BaO2 is an iron gray or white powder. It is slowly decomposed in air, forming the hydroxide and oxygen. It does not dissolve in water, but can slowly hydrolyze, forming hydrogen peroxide in solution. Barium peroxide is a strong oxidizing agent and will explode if direct contact with organic matter occurs. Therefore, barium peroxide is always diluted to form a slurry before usage. Barium peroxide is a strong oxidizing agent that is used for bleaching. Barium peroxide contains O22- subunits wherein the oxygen atoms bond to each other as well as to the barium.

Verwenden

Bariumperoxide is used as a hydrogen peroxide source and oxygen oxidant, as well as a bleaching agent. Its main usage has been for making hydrogen peroxide and oxygen, in organic syntheses, fabric printing and dyeing. Barium peroxide is available commercially, primarily as the oxctahydrate (which is the more stable form of this peroxide).

Verwenden

Barium peroxide (BaO2) is a grayish-white dry powder that makes an excellent bleaching agent that can be stored in paper packages. Its bleaching qualities are released when mixed with water.

Verwenden

Bleaching animal substances, vegetable fibers and straw; glass decolorizer; manufacture of H2O2 and oxygen; dyeing and printing textiles; with powdered aluminum in welding; in cathodes; in igniter compositions. Oxidizing agent in organic synthesis.

Definition

barium peroxide: A dense offwhitesolid, BaO2, prepared by carefullyheating barium oxide inoxygen; r.d. 4.96; m.p. 450°C. It is used as a bleaching agent. Withacids, hydrogen peroxide is formedand the reaction is used in the laboratorypreparation of hydrogen peroxide.

Vorbereitung Methode

Barium peroxide, BaO2, was the first-known peroxo compound. It was used until mid-1900 in the manufacture of oxygen by the Brin process and of hydrogen peroxide by the Thenard reaction.

synthetische

Barium peroxide is best prepared by reacting barium nitrate with sodium peroxide in a cold solution:
Ba(NO3)2+Na2O2+xH2O→BaO2·xH2O+2NaNO3
The hydrated form is usually the octahydrate. If the anhydrate is desired, the hydrated peroxide is dried and then sintered at 350°C for 10 min or less:
4BaO2·xH2O+ heat→2BaO+2BaO2+xH2O+O2
About equal amounts of oxide and peroxide form. The ratio is a function of the time and temperature of heating. To separate the two forms, the heated mass is plunged into a large volume of water where the hydroxide is formed. The peroxide is insoluble whereas the hydroxide is soluble, allowing the separation of the two by filtration. The peroxide is then vacuum dried.

Allgemeine Beschreibung

A grayish-white granular solid. Insoluble in water. Noncombustible, but accelerates the burning of combustible material. Mixture with finely divided combustible material may be explosive. Mixtures with combustible material may be ignited by friction or contact with moisture.

Air & Water Reaktionen

Decomposed by water. Insoluble in water.

Reaktivität anzeigen

Barium peroxide is a strong oxidizing agent. Contact with water can produce a temperature and oxygen concentration high enough to ignite organic materials [Bretherick's, 5th ed., 1995, p. 94]. Reacts explosively with acetic anhydride due to the formation of acetyl peroxide [Rust, 1948, p. 337]. Ignites when mixed with powdered aluminum, powdered magnesium or calcium-silicon alloys. Wood may ignite with friction from the peroxide. Decomposes when heated to 700°C to produce barium oxide and pure oxygen [Sax, 9th ed., 1996, p. 317]. Forms highly reactive mixtures with fuel-type materials.

Hazard

Oxidizing material. Fire and explosion risk in contact with organic materials. Keep cool and dry. Toxic by ingestion, skin irritant.

Health Hazard

Inhalation causes irritation of mucous membranes, throat, and nose. Contact with eyes or skin causes severe burns. Ingestion causes excessive salivation, vomiting, colic, diarrhea, convulsive tremors, slow, hard pulse, and elevated blood pressure; hemorrhages may occur in the stomach, intestines, and kidneys; muscular paralysis may follow.

Brandgefahr

Behavior in Fire: Can increase intensity of fire.

Sicherheitsprofil

A poison via subcutaneous route. A powerful oxidtzer. Explodes on contact with acetic anhydride. Ignites when mixed with calcium-silicon alloys, powdered aluminum, powdered magnesium, water + organic compounds. Mixtures with propane react violently when heated. The powder ignites when heated to 265℃ with selenium. Wood ignites with friction from the peroxide. Incompatible with H2S, water, peroxyformic acid, hydroxylamine solution, mixture of (Mg + Zn + Ba(NO3)2), and organic matter. See also BARIUM COMPOUNDS (soluble) and PEROXIDES, INORGANIC.

mögliche Exposition

Is used as a bleaching agent; in making hydrogen peroxide, oxygen; in aluminum welding; in textile dyeing and for bleaching fibers; animal substances.

Versand/Shipping

UN1449 Barium peroxide, Hazard Class: 5.1; Labels: 5.1—Oxidizer, 6.1—Poisonous materials.

Inkompatibilitäten

A strong oxidizer. Keep away from organic and combustible materials (such as wood, paper, oil, fuels, and other easily oxidized materials) and peroxyformic acid, hydrogen sulfide and hydroxylamine solutions, since violent reactions occur.

Waste disposal

Dispose of contents and container to an approved waste disposal plant. All federal, state, and local environmental regulations must be observed. Contact your local or federal environmental protection agency for specific recommendations.
