Chemische Eigenschaften
White, crystalline powder; becomes violet
on exposure to light. Slightly soluble in water; insoluble in
alcohol, ammonium hydroxide.
Verwenden
Catalyst (chlorination), suntan lamp monitors.
synthetische
Thallium chloride may be prepared by heating the metal with chlorine.
Allgemeine Beschreibung
White, crystalline powder, becomes violet on exposure to light. Used as a catalyst in chlorinations and in suntan lamps.
Reaktivität anzeigen
Fluorine and THALLIUM(I) CHLORIDE react violently, melting the product [Mellor Supp. 1:63 1956]. When heated to decomposition, THALLIUM(I) CHLORIDE emits very toxic fumes of chloride and thallium. Thallium(I) chloride is vigorously attacked by cold fluorine. A mixture of potassium and THALLIUM(I) CHLORIDE produces a weak explosion on impact [EPA, 1998].
Hazard
Thallium chloride is highly toxic. Acute toxic effects are those of thallium poisoning.
Health Hazard
(Non-Specific -- Thallium Salts) Poisonous if swallowed. Inhalation of dust is poisonous.
Brandgefahr
(Non-Specific -- Thallium Salts) Fire may produce irritating or poisonous gases. When heated to decomposition, THALLIUM(I) CHLORIDE emits very toxic fumes of chloride and thallium. Thallium(I) chloride is vigorously attacked by cold fluorine. A mixture of potassium and THALLIUM(I) CHLORIDE produces a weak explosion on impact.
Sicherheitsprofil
Poison by ingestion and intraperitoneal routes. An experimental teratogen. Mutation data reported. Incompatible with F2. When heated to decomposition it emits very toxic fumes of Cland T1. See also THALLIUM COMPOUNDS and CHLORIDES.
läuterung methode
Crystallise it from 1% HCl and wash it until acid-free, or crystallise it from hot water (50mL/g), then dry it at 140o and store it in brown bottles. Also purify it by subliming it in a vacuum, followed by treatment with dry HCl gas and filtering while molten. (It is soluble in 260 parts of cold water and 70 parts of boiling water). POISONOUS.
