Carbon tetrabromide Usage And Synthesis
  • Chemical PropertiesCrystalline colorless
  • Chemical PropertiesCarbon tetrabromide, is a colorless powder, white crystalline solid, or yellow-brown crystals. Slight odor
  • UsesOrganic synthesis.
  • UsesCarbon tetrabromide is used to a limited extent as a chemical intermediate. It has been isolated from red algae, Asparagopsis toxiformis, found in the ocean near Hawaii.
  • DefinitionChEBI: A one-carbon compound substituted by 4 bromo groups.
  • General DescriptionA colorless crystalline solid. Much more dense than water and insoluble in water. Toxic by ingestion. Vapors are narcotic in high concentration. Used to make other chemicals.
  • Air & Water ReactionsInsoluble in water.
  • Reactivity ProfileCarbon tetrabromide is incompatible with the following: Strong oxidizers, hexacyclohexyldilead, lithium .
  • HazardA poison; narcotic in high concentration. Liver damage, eye, skin, and upper respiratory tract irritant.
  • Health HazardHighly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
  • Fire HazardNon-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways.
  • Safety ProfilePoison by subcutaneous and intravenous routes. Narcotic in high concentration. Mixture with Li particles is an impact-sensitive explosive. Explodes on contact with hexacyclohexylddead. When heated to decomposition it emits toxic fumes of Br-. See also CHLORINATED HYDROCARBONS, ALIPHATIC.
  • Potential ExposureCBr4 is used in organic synthesis.
  • ShippingUN2516 Carbon tetrabromide, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
  • Purification MethodsReactive bromide is removed from CBr4 by refluxing with dilute aqueous Na2CO3, then steam distilling, crystallising from EtOH, and drying in the dark under vacuum. [Sharpe & Walker J Chem Soc 157 1962.] It can be sublimed at 70o and low pressure. [Beilstein 1 IV 85.]
  • IncompatibilitiesIncompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, lithium and hexacyclohexyldiilead, since violent reactions may occur.
  • Waste DisposalPurify by distillation and return to suppliers.
