タリウム(I) 化学特性,用途語,生産方法

• 外観

  白色の結晶性粉末

• 溶解性

  水に可溶 (4.87g/100ml 20℃)。

• 用途

  農薬(殺そ剤) (NITE CHRIP)

• 用途

  高純度金属化合物。

• 使用上の注意

  純度は金属ベースで差数法によって算出したもので、重量又は容量分析等の化学的方法によるものではありません。使用目的により、正確な含量が必要な場合は、それらの方法によって測定する必要があります。

• 化学的特性

  white fine crystalline powder or needles

• 使用

  Thallium(I) sulfate is used as a precursor to thallium(I) sulfide, which exhibits high electrical conductivity when exposed to infrared light. It is further used in photocells. It is also mixed with selenium and arsenic to produce low melting glasses.

• 調製方法

  Commercial sources are flue dusts, either from pyrite (FeS2) burners or from lead and zinc smelters and refiners, as a byproduct of cadmium production at the rate of a few thousand pounds per year. In the flue dusts thallium occurs largely as a sulfate, which is extracted with hot water or dilute sulfuric acid. The purification of thallium is accomplished by taking advantage of the difference in solubility of certain thallium compounds and the impurities. Traces of zinc, copper, cadmium, lead, and indium are removed by dissolving the thallium in and precipitating the impurities with hydrogen sulfide.

• 一般的な説明

  Odorless white rhomboid prisms or a dense white powder. Density 6.77 g / cm3. Melting point 1170°F (632°C). Extremely toxic by ingestion. Very toxic by skin absorption and ingestion. A slow acting cumulative poison. Used as a rat poison, and an ant bait. Also used for analysis (testing for iodine in the presence of chlorine) and ozonometry. Not registered as a pesticide in the U.S.

• 空気と水の反応

  Soluble in water.

• 反応プロフィール

  THALLIUM(I) SULFATE has weak oxidizing and weak reducing powers. Redox reactions can however still occur.

• 健康ハザード

  Rated as extremely toxic. The probable oral lethal dose in humans is 5 to 50 mg/kg, or between 7 drops and 1 teaspoon for a 150-pound person. The mean lethal dose in an adult is probably about 1 gm of THALLIUM(I) SULFATE. Chronic exposure causes hair loss starting 10 days after exposure and complete baldness in about a month.

• 火災危険

  When heated to decomposition, THALLIUM(I) SULFATE emits very toxic fumes of thallium and sulfur oxide.

• 安全性プロファイル

  Human poison by ingestion. Experimental poison by ingestion and subcutaneous routes. Human systemic effects by ingestion: ataxia, change in heart rate, excitement, eye changes, irritability, nausea or vomiting, nerve or sheath structural changes, somnolence, wakefulness. Experimental reproductive effects. When heated to decomposition it emits very toxic fumes of T1 and SOx. Used as a rat poison, ant bait, and a reagent in analytical chemistry. See also THALLIUM COMPOUNDS and SULFATES.

• 発がん性

  Thallium is not classifiable with respect to carcinogenicity due to a lack of relevant human and animal studies. Several subchronic and chronic animal studies on thallium and compounds are available; however, they were not designed to examine carcinogenic end points.

• 純化方法

  The sulfate crystallises from hot water (7mL/g) by cooling; then dry it under vacuum over P2O5. It is POISONOUS.
