Bromoform Usage And Synthesis |
Chemical Properties | colourless to yellow liquid |
General Description | A colorless liquid with a chloroform-like odor. Denser than water (density: 2.9 g / cm3 ) and slightly soluble in water. Hence sinks in water. Nonflammable. Toxic by ingestion, inhalation and skin absorption. A lachrymator. Used as a solvent and to make pharmaceuticals. Often stabilized with 1 to 3% ethanol. |
Air & Water Reactions | Slightly soluble in water. |
Reactivity Profile | Heating Bromoform to decomposition produces highly toxic fumes of carbon oxybromide (carbonyl bromide) and hydrogen bromide [Sax, 9th ed., 1996, p. 519]. Reaction with powdered potassium or sodium hydroxide, Li or Na/K alloys, is violently exothermic [Weizmann, C. et al., J. Am Chem. Soc., 1948, 70, p. 1189]. Explosive reaction with crown ethers in the presence of potassium hydroxide [Le Goaller, R. et al., Synth. Comm., 1982, 12, p. 1163]. |
Health Hazard | Harmful if inhaled, swallowed, contacts skin or eyes or is absorbed through skin. It is a lachrymator, respiratory irritant, a narcotic and an hepatotoxin. Prolonged exposure may cause dermatitis. Inhalation causes irritation of nose and throat; provokes the flow of tears and saliva and reddening of the face. Ingestion may cause dizziness, disorientation and slurred speech, unconsciousness and death. |
Fire Hazard | Behavior in Fire: May decompose to produce toxic gases and vapor such as hydrogen bromide and bromine. |
