과산화바륨 C화학적 특성, 용도, 생산

화학적 성질

greyish white powder

화학적 성질

Barium peroxide is a grayish-white powder.

물리적 성질

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.

용도

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).

용도

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.

제조 방법

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 a

정의

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.

일반 설명

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.

공기와 물의 반응

Decomposed by water. Insoluble in water.

반응 프로필

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.

위험도

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

건강위험

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.

화재위험

Behavior in Fire: Can increase intensity of fire.

Safety Profile

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.

잠재적 노출

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

응급 처치

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

운송 방법

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

비 호환성

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.

폐기물 처리

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.
