Dibromomethane Usage And Synthesis
Chemical Propertiescolourless liquid
Chemical PropertiesMethylene bromide is a colorless liquid with a sweet, pleasant odor.
UsesOrganic synthesis, solvent.
UsesDibromomethane is used as solvent in organic synthesis. It acts as an intermediate in the manufacture of specialty chemicals, agrochemicals and pharmaceuticals. It is useful as extractant and utilized for the determination of 5-nitroimidazoles (5-NDZ) in environmental waters. It is involved in the convertion of catechols to their methylenedioxy derivatives.
DefinitionChEBI: A member of the class of bromomethanes that is methane substituted by two bromo groups. It is produced by marine algae.
General DescriptionA 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 ReactionsInsoluble in water.
Reactivity ProfileHalogenated 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 HazardINHALATION: Anesthetic effects, nausea and drunkenness. CONTACT WITH SKIN AND EYES: Skin irritation of eyes and nose.
Fire HazardSpecial Hazards of Combustion Products: Dissociation products generated in a fire may be irritating or toxic.
Safety ProfileA 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 ExposureMethylene bromide is used as a solvent and as a chemical intermediate.
ShippingUN2664 Dibromomethane, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
IncompatibilitiesMixture 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 DisposalConsult 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
