carbon bromide is a colorless crystalline substance with a slightly distinctive odor. It has a density of 3.42 g /cm3 in its solid state.
carbon bromide can be prepared by the direct reaction of carbon dioxide with fluorine gas at high temperatures (7.8.12). The resulting carbon-fluorine compound reacts with a variety of halogens, producing a family of compounds that are commonly called ‘halogenated methanes’ or ‘Freons’. These molecules are very stable, and their C-H bonds are not broken by photolysis in the lower atmosphere. They do not decompose in the troposphere, and so can be transported to the stratosphere, where they contribute to the formation of ozone.
The chemical is also used in the synthesis of isocyanates from alkyl or aryl amines, (7.8.11). The electrophilic character of phosgene allows it to introduce the equivalent of CO2+ into a carbonyl group, but it is less commonly used for this purpose than thionyl chloride, because the former is much cheaper and safer to handle.
Exposure to carbon tetrachloride vapor may cause headaches, mental confusion, lethargy, nausea and vomiting. Long-term exposure can lead to bronchitis and jaundice. Skin contact can cause dermatitis. Carbon tetrachloride is highly toxic when inhaled. Concentrations in excess of 0.1 ppm can cause headaches, drowsiness, depression, loss of appetite, and nausea and vomiting. Concentrations of 0.01 ppm or greater in the eyes can cause severe pain and irritation, as well as corneal damage. Chronic exposure can cause pulmonary and laryngeal changes in rats.
