Dibromomethane Usage And Synthesis

Chemical Properties

colourless liquid

Chemical Properties

Methylene bromide is a colorless liquid with a sweet, pleasant odor.

Uses

Organic synthesis, solvent.

Definition

ChEBI: A member of the class of bromomethanes that is methane substituted by two bromo groups. It is produced by marine algae.

General Description

A colorless liquid with a pleasant odor. Insoluble in water and denser than water. May be toxic by ingestion. Used as a solvent and as a motor fuel.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Halogenated aliphatic compounds, such as Dibromomethane, are moderately or very reactive. Reactivity generally decreases with increased degree of substitution of halogen for hydrogen atoms. Low molecular weight haloalkanes are highly flammable and can react with some metals to form dangerous products. Materials in this group are incompatible with strong oxidizing and reducing agents. Also, they are incompatible with many amines, nitrides, azo/diazo compounds, alkali metals (potassium), and epoxides.

Health Hazard

INHALATION: Anesthetic effects, nausea and drunkenness. CONTACT WITH SKIN AND EYES: Skin irritation of eyes and nose.

Fire Hazard

Special Hazards of Combustion Products: Dissociation products generated in a fire may be irritating or toxic.

Safety Profile

A poison. Moderately toxic by subcutaneous route. Mdly toxic by inhalation. Mutation data reported. mxtures with potassium explode on light impact. When heated to decomposition it emits toxic fumes of Br-. See also BROMIDES

Potential Exposure

Methylene bromide is used as a solvent and as a chemical intermediate.

Shipping

UN2664 Dibromomethane, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

Incompatibilities

Mixture with potassium forms a shocksensitive explosive. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, sodium amide, strong acids, strong bases, alkaline earth metals, aluminum, magnesium. The substance decomposes on contact with hot surfaces producing hydrogen bromide

Waste Disposal

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform to EPA regulations governing storage, transportation, treatment, and waste disposal
