• 化学的特性

  Selenium oxychloride is a colorless to yellowish liquid. Fumes in air.

• 物理的性質

  Pale yellow or colorless liquid; corrosive; refractive index 1.651 at 20°C; density 2.42 g/mL at 22°C; freezes at 8.5°C; boils at 176.4°C; decomposes at 176.4°C; decomposes in water forming hydrochloric acid and selenious acid; soluble in carbon disulfide, carbon tetrachloride, chloroform, benzene, and toluene.

• 使用

  selenium oxychloride is used as solvent.

• 調製方法

  Selenium oxychloride (SeOCl2) is a powerful solvent, chlorinating agent, and resin plasticizer used in the chemical industry.

• 一般的な説明

  A colorless to light-colored liquid. Insoluble in water and denser than water. Contact may severely irritate skin, eyes and mucous membranes. May be toxic by ingestion, inhalation and skin absorption. Used to make other chemicals.

• 空気と水の反応

  Fumes in air. Insoluble in water and denser than water. Decomposed in water or moist air to form hydrochloric acid and selenious acid [Merck 11th ed. 1989].

• 反応プロフィール

  Red phosphorus reacts in the cold with SELENIUM OXYCHLORIDE evolving light and heat; white phosphorus reacts explosively [Mellor 10:906 1946-47]. When potassium is brought into contact with SELENIUM OXYCHLORIDE in the cold, an explosion occurs [Mellor 10:908 1946-47]. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291]. Powdered antimony ignites on contact with the chloride, [Mellor, 1947, Vol. 10, 906]. With metal oxides, i.e. silver oxide, light is evolved and heat sufficient to decompose the mixture, [Mellor, 1947, Vol. 10, 909].

• 危険性

  Extremely hazardous, toxic irritant, poison, severe vesicant.

• 健康ハザード

  SELENIUM OXYCHLORIDE is very toxic and may cause death or permanent injury after very short exposures to small quantities. Inhalation of small quantities may be corrosive and irritating to the respiratory tract. It can burn and irritate the skin and eyes and cause burns when ingested. Long-term exposure to selenium compounds may be a cause of amyotrophic lateral sclerosis in humans. Populations at special risk include those with a history of dermatitis, chronic bronchitis, skin allergies, respiratory tract infections, liver or kidney disease, jaundice, or albuminuria. Women of child-bearing age are also considered at risk.

• 火災危険

  When SELENIUM OXYCHLORIDE is heated to decomposition, or in contact with acids or acid fumes, highly toxic chloride and selenium fumes are evolved. Hydrochloric acid and selenious acid are produced by reaction with water. Decomposed by water. Reacts violently with powdered antimony, red and white phosphorus, disilver oxide, lead oxides, and potassium. Avoid water, moist air.

• 安全性プロファイル

  Poison by skin contact and subcutaneous routes. Human systemic effects by skin contact with very small amounts: primary irritant, corrosive. Explodes on contact with potassium, white phosphorus. Ignites on contact with antimony. Vigorous reaction with metal oxides (e.g., silver oxide, lead@) oxide, lead(Ⅳ) oxide, lead(II)(IV) oxide). When heated to decomposition it emits very toxic fumes of Cland Se. See also SELENIUM COMPOUNDS and CHLORIDES.

• 職業ばく露

  This material is used as a solvent for many substances, including metals and as a chlorinating agent; and resin plasticizer; as an ionizing solvent; for monochlorination of ketones.

• 輸送方法

  UN2879 Selenium oxychloride, Hazard class: 8; Labels: 8-Corrosive material, 6.1-Poisonous material.

• 不和合性

  Water and air reactive releasing strong acids. The aqueous solution is a strong acid and oxidizer.Reacts violently with bases, reducing agents, hydrides, powdered antimony, red, and white phosphorus, disilver oxide, lead oxide; powdered metals, and potassium. Note: Never pour water into this substance; when dissolving or diluting always add it slowly to the water
