BROMOACETONE 1-bromo-2-propanon 2-propanone,1-bromo-
Chemical Properties | Colorless liquid when pure, rapidly becomes violet even in absence of air. Soluble in ace- tone, alcohol, benzene, and ether; slightly soluble in water. |
Uses | Chemical war gas. |
Definition | ChEBI: An alpha-bromoketone that is acetone in which one of the hydrogens is replaced by a bromine atom. A poweful lachrymator, it was formerly used as a chemical weapon. |
General Description | A clear colorless liquid turning violet on standing, even in the absence of air, and decomposing to a black resinous mass on long standing. Denser than water and poorly soluble in water. Hence sinks in water. A violent lachrymator--low concentrations are very irritating to the eyes; high concentrations or prolonged exposure at lower concentrations may have adverse health effects. Very toxic by inhalation. Contact with the liquid causes painful burns. Used as a chemical war gas. |
Air & Water Reactions | Highly flammable. Soluble in water. |
Reactivity Profile | BROMOACETONE decomposes on standing. |
Hazard | Toxic by inhalation and skin contact. A lachrymator gas, strong irritant. |
Health Hazard | Very powerful lachrymator and upper respiratory tract irritant. Intensely irritating to the eyes, nose, throat, and lungs. Corrosive to the skin. |
Fire Hazard | Special Hazards of Combustion Products: Toxic fumes of Bromine |
Safety Profile | A poisonous gas. Moderately toxic to humans by inhalation. When heated to decomposition it emits toxic fumes of Br-. See also BROMIDES. |
Purification Methods | Stand bromoacetone over anhydrous CaCO3, filter, distil it under low vacuum, and store it with CaCO3 in the dark at 0o. [Levene Org Synth Coll Vol II 88 1943.] Violently LACHRYMATORY and skin IRRITANT. |
