THALLIUM(I) ACETATE Usage And Synthesis
Chemical PropertiesWhite to off-white fine crystalline powder
UsesAcetic Acid Thallium(1+) Salt, is a Thalum salt, considere to be a hazardous material.It can be used as in Chemical Synthesis, Micro/NanoElectronics, and Materials Science.
UsesThallium acetate is used in high specific gravity solutions to separate ore constituents by flotation. It was formerly used as a depilating agent by dermatologists via oral administration in cases of ringwormof the scalp, causinga number ofdeathsand poisonings.Thallium(I) acetate (0.1M) is used to enhance phosphorescence emission on laserinduced room-temperature phosphorimetry.
UsesRodenticide, insecticide; fireworks dye; in optical glass; depilatory.
DefinitionChEBI: An acetate salt comprising equal numbers of acetate and thallium ions.
Production MethodsThallium acetate is prepared from thallium(I) hydroxide or carbonate and acetic acid, which are then evaporated and recrystallized from alcohol.
General DescriptionWhite odorless crystalline solid. Density 3.68 g / cm3. A dangerous poison.
Air & Water ReactionsDeliquescent. Soluble in water.
Reactivity ProfileTHALLIUM(I) ACETATE gives aqueous solutions that are basic (neutralize acids). These neutralizations generate only a little heat. Neither a strong reducing agent nor oxidizing agent, but can serve as both.
Health HazardThallium is one of the more toxic elements both as an acute and a chronic poison. Effects of exposure are cumulative and onset of symptoms may be delayed 12 to 24 hours. May be fatal if inhaled, ingested or absorbed through the skin. Irritating to skin and eyes. Readily absorbed through the skin and digestive tract. Ingestion of soluble thallium compounds has caused many deaths. Ingestion of sublethal quantities may cause nausea, vomiting, diarhea, abdominal pain, and bleeding from the gut accompanied or followed by drooping eyelids, crossed eyes, weakness, numbness, tingling of arms and legs, trembling, tightness and pain in the chest. Loss of hair may occur in two to three weeks. Severe intoxication may cause prostration, rapid hearbeat, convulsions, and psychosis. Some effects may be permanent.
Safety ProfileHuman poison by ingestion. Experimental poison by ingestion, intravenous, intraperitoneal, and subcutaneous routes. An experimental teratogen. Mutation data reported. When heated to decomposition it emits toxic fumes of T1. See also THALLIUM COMPOUNDS.
