Chemische Eigenschaften
White to off-white fine crystalline powder
Verwenden
Thallium 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.
Vorbereitung Methode
Thallium acetate is prepared from thallium(I) hydroxide or
carbonate and acetic acid, which are then evaporated and
recrystallized from alcohol.
Definition
ChEBI: An acetate salt comprising equal numbers of acetate and thallium ions.
Allgemeine Beschreibung
White odorless crystalline solid. Density 3.68 g / cm3. A dangerous poison.
Air & Water Reaktionen
Deliquescent. Soluble in water.
Reaktivit?t anzeigen
THALLIUM(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 Hazard
Thallium 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.
Sicherheitsprofil
Human 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.
