Hazard Information

Chemical Properties

Sodium perchlorate, NaCl04, is a flammable, white crystalline deliquescent solid that melts at 482 °C(899.6 °F). Soluble in water and alcohol, it is used as an analytical reagent. Sodium perchlorate is explosive in nature when in contact with concentrated sulfuric acid and finds use in explosives and jet fuels.

Uses

A chaotropic agent used in DNA extraction and hybridization

Uses

It is used in electrolyte; oxidimetric standard.

Definition

ChEBI: An inorganic sodium salt comprising equal numbers of sodium and perchlorate ions.

General Description

White crystalline solid. Noncombustible but will accelerate the burning of combustible materials. If large quantities are involved in a fire or the combustible material is finely divided, an explosion may result. Prolonged exposure to fire or heat may result in an explosion. Used in chemical analysis and in explosives.

Reactivity Profile

SODIUM PERCHLORATE(7601-89-0) is a strong oxidizing agent. Explosively decomposed at over 130°C [Merck 11th ed. 1989]. A mixture with powdered magnesium is a friction-sensitive mixture [Safety Eng. Reports 1947]. A mixture with ammonium nitrate is used as an explosive [Mellor 2 Supp. 1:608 1956]. A 1:1 mixture of the perchlorate and hydrazine exploded upon grinding, [Chem. Abs., 1969, 70, 53524].

Air & Water Reactions

Water soluble.

Hazard

Dangerous fire and explosion risk in contact with organic materials and sulfuric acid.

Health Hazard

Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.

Fire Hazard

These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.

Purification Methods

Because its solubility in water is high (2.1g/mL at 15o) and it has a rather low-temperature coefficient of solubility, sodium perchlorate is usually crystallised from acetone, MeOH, water/ethanol or dioxane/water (33g dissolved
