THALLIUM(I) BROMIDE Usage And Synthesis
DescriptionThallium bromide is a yellow-white solid and hygroscopic. It is similar to silver bromide. It gets darker when light shines on it. It is very toxic, like all thallium compounds. It does not dissolve in water. Thallium bromide is used in gamma ray and x-ray detectors and also in semiconductors. Prolonged period of exposure to thallium compounds has been reported to cause adverse health effects such as joint pain, severe pain in legs, loss of appetite, fatigue, and albuminuria.
Chemical PropertiesTHALLIUM(I) BROMIDE is yellow crystalline powder
UsesTHALLIUM(I) BROMIDE is used for mixed crystals with thallium iodide for infrared radiation transmitters used in military detection devices.
UsesThallium(I) bromide is used as Chemical reagents and pharmaceutical intermediates.
Safety ProfilePoison by ingestion and subcutaneous routes. Reacts violently with Na, K. When heated to decomposition it emits very toxic fumes of Brand T1. See also BROMIDES and THALLIUM COMPOUNDS.
Purification MethodsThallous bromide (20g) is purified by refluxing for 2-3hours with water (200mL) containing 3mL of 47% HBr. It is then washed until acid-free, heated to 300o for 2-3hours and stored in brown bottles. It solubility in H2O (w/w) is 0.034% at 0o, 0.048% at 20o, and 0.204% at 100o.
