AMMONIUM PERMANGANATE

Chemical Properties

Ammonium permanganate is a violet-brown or dark purple crystalline (sugar-like or sand-like) solid.

Chemical Properties

Crystal or powder form, having a metallic sheen in rich violet-brown or dark-purple shades, soluble in water.

General Description

A crystal or powder with a rich violet-brown or dark purple metallic sheen. Toxic by ingestion or inhalation of dust.

Air & Water Reactions

Soluble in water

Reactivity Profile

Dry AMMONIUM PERMANGANATE may explode on shock, friction or heating [Hawley]. Mixtures with acetic acid or acetic anhydride may explode if not kept cold [Von Schwartz p 34 1918]. Explosions can occur when permanganates that have been treated with sulfuric acid come in contact with benzene, carbon disulfide, diethyl ether, ethyl alcohol, petroleum, or organic matter.

Hazard

May explode on shock or on exposure to heat. Toxic by ingestion or by inhalation of dust or fume. Powerful oxidizer.

Safety Profile

Probably an irritant. A powerful oxidizer. Moderately flammable by chemical reaction with reducing agents. Explosive when shocked or warmed to 60°. Can be exploded by percussion. When heated to decomposition it emits toxic fumes of NOx and NH3. Incompati

Potential Exposure

This material is used in bleaching and dyeing operations in the textile and leather industries.

Shipping

UN0473 Substances, explosive, n.o.s., Hazard Class: 1.1 A; Labels:1.1A-Explosive (with a mass explosion hazard); A-Substances which are expected to mass detonate very soon after fire reaches them, Technical Name Required. UN3085 Oxidizing solid, corrosive, n.o.s., Hazard Class: 5.1; Labels: 5.1-Oxidizer, 8-Corrosive material. Technical Name Required.

Incompatibilities

Explosive; a strong oxidizing agent. Contact with reducing agents; fuels and other combustible materials; heat, or friction may cause a violent reaction. Ammonium permanganate, when dry, may explode from shock, friction or heating. Incompatible with acetic acid,acetic anhydride, benzene, carbon disulfide, diethyl ether, ethyl alcohol, petroleum, combustibles, or organic matter.

Waste Disposal

Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number N450, must conform with USEPA regulations for storage, transportation, treatment and disposal of waste. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill. Dispose of contents and container to an approved waste disposal plant. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office. All federal, state, and local environmental regulations must be observed. Do not discharge into drains or sewers.
