化学的特性
Antimony trifluoride is a noncombustible,
odorless, white to gray crystalline solid.
使用
To catalyze fluorinations by HF, manufacture of chlorofluorides, in dyeing, usually in form of double salts, e.g., antimony sodium fluoride or antimony fluoride and ammonium sulfate double salt, manufacture of pottery and porcelains.
一般的な説明
Antimony trifluoride solution is the white to gray crystalline solid dissolved in water. Antimony trifluoride is corrosive to metals and tissue. Antimony trifluoride is used in ceramics and to make other chemicals.
空気と水の反応
Water slowly hydrolyzes antimony fluoride to form antimony (III) oxide. The dry powdered oxide ignites on heating in air [Mellor Vol. 9 425.1939].
反応プロフィール
ANTIMONY TRIFLUORIDE is a colorless, solid compound, toxic and corrosive. When heated to decomposition, Antimony trifluoride emits very toxic fumes of fluoride and metallic antimony [Lewis, 3rd ed., 1993, p. 83].
危険性
Strong irritant to eyes and skin.
健康ハザード
TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
火災危険
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Vapors may accumulate in confined areas (basement, tanks, hopper/tank cars etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water.
安全性プロファイル
Poison by
subcutaneous route. Corrosive to skin and
eyes. See also FLUORIDES and
ANTIMONY COMPOUNDS. When
heated to decomposition it emits very toxic
fumes of Fand Sb
職業ばく露
It is used in dyeing; to make porcelain
and pottery; and as a fluorinating agent.
輸送方法
UN1549 Antimony compounds, inorganic, solid,
n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials,
Technical Name Required.
純化方法
It crystallises from MeOH to remove oxide and oxyfluoride, then it is sublimed under vacuum in an aluminium cup on to a water-cooled copper condenser. Its solubility is 443g/100g in H2O at 20o and 562g/100g in H2O at 30o with partial hydrolysis. [Woolf J Chem Soc 279 1955, Kwasnik in Handbook of Preparative Inorganic Chem (Ed. Brauer) Academic Press Vol I p 199 1963].
不和合性
Hot perchloric acid.
廃棄物の処理
Consult with environmental
regulatory agencies for guidance on acceptable disposal
practices. Generators of waste containing this contaminant
(≥100 kg/mo) must conform with EPA regulations governing
storage, transportation, treatment, and waste disposal.
