BARIUM PERCHLORATE Usage And Synthesis

Description

Barium perchlorate is a white crystalline solid.Molecular weight=336.2; Freezing/Melting point=400℃(trihydrate); 505℃ (anhydrous). Hazard Identification(based on NFPA-704 M Rating System): Health 2,Flammability 0, Reactivity 0. Highly soluble in water;solubility=200 g/100 mL at 33℃

Chemical Properties

White Crystalline Powder

Uses

Ribonuclease determination and effective desiccant.

Uses

Barium perchlorate, anhydrous is used to make explosives. It is also used as desiccant, ribonuclease determination.

Uses

In the determination of ribonuclease; as absorbent for water in C and H analysis.

General Description

A white crystalline solid. Noncombustible, but accelerates burning of combustible materials. May explode if large quantities are involved in a fire or the combustible material is finely divided. Prolonged exposure to fire or heat may result in an explosion. Used to make explosives.

Air & Water Reactions

Water soluble.

Reactivity Profile

Reflux heating of BARIUM PERCHLORATE with alcohols yields perchlorate esters, which are highly explosive [Kirk-Othmer 2nd ed. 5:75 1963]. A strong oxidizing agent. May react violently with organic materials.

Health Hazard

Inhalation or contact with eyes or skin causes irritation. 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.

Fire Hazard

Behavior in Fire: Increases the intensity of fire. Containers may explode.

Safety Profile

A poison. An unstable material. An oxidizer. When refluxed with an alcohol highly explosive alkyl perchlorates are formed. When heated to decomposition it emits toxic fumes of Cl-. A desiccant. See also PERCHLORATES and BARIUM COMPOUNDS.

Potential Exposure

It is used to make explosives and inexperimental rocket fuels.

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seekmedical attention immediately. If this chemical contactsthe skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove fromexposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing hasstopped and CPR if heart action has stopped. Transferpromptly to a medical facility. When this chemical hasbeen swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

storage

Color Comables and combustibles. Store in tightly closed containersin a cool, well-ventilated area away from heat sources,sources of shock, or the incompatible materials cited above.Sources of ignition, such as smoking and open flames, areprohibited where Barium perchlorate is handled, used, orstored. See OSHA Standard 1910.104 and NFPA 43A Codefor the Storage of Liquid and Solid Oxidizers for detailedhandling and storage regulationsde—Yellow: Reactive Hazard; Store in alocation separate from other materials, especially flam

Shipping

Barium perchlorate requires a shipping labelof “OXIDIZER, POISONOUS/TOXIC MATERIALS.”This material falls in Hazard Class 5.1 and PackingGroup II.[19, 20]

Purification Methods

Recrystallise the perchlorate twice from water. [Schmeisser in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 320 1963.]

Incompatibilities

An oxidizing agent. Contact with organicand combustible materials (such as paper, wood, and oil),finely divided metals (specifically magnesium and aluminum), sulfur, calcium hydride, and strontium hydride sinceviolent reactions occur
