アンチモンペンタクロリド 化学特性,用途語,生産方法
用途
フレオンガス触媒,塩素化触媒,半導体製造用ドーパント
特徴
三角両錐.2.43 KでSb-Cl(底面)229 pm,Sb-Cl(軸方向)234 pm
化学的特性
colourless to light yellow oily liquid
物理的性質
Antimony pentachloride is prepared by passing chlorine gas into molten antimony trichloride:
SbCl
3 + Cl
2 →SbCl
5or by the reaction of the element with excess chlorine:
2 Sb + 5 Cl
2 → 2 SbCl
5.
使用
Antimony(V) chloride is used as a catalyst and an analytical reagent for testing alkaloids and cesium. It is also used as a polymerization catalyst as well as involved in the chlorination of organic compounds. It acts as a Lewis acid and a strong oxidizing agent.
一般的な説明
A reddish-yellow fuming liquid with a pungent odor. Fumes are irritating to the eyes and mucous membranes. Solidifies at 37°F. Corrosive to metals and tissue. Used to make other chemicals, and in chemical analysis.
空気と水の反応
Fumes in air to form hydrochloric acid. Reacts with water to yield heat and antimony pentaoxide (Sb2O5) and hydrochloric acid [Merck 11th ed. 1989].
反応プロフィール
Acidic salts, such as ANTIMONY PENTACHLORIDE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
危険性
Corrosive, fumes in moist air, reacts
strongly with organics.
健康ハザード
Inhalation causes irritation of nose and throat. Contact of liquid with eyes or skin causes severe burns. Ingestion causes vomiting and severe burns of mouth and stomach. Overexposure by any route can cause bloody stools, slow pulse, low blood pressure, coma, convulsions, cardiac arrest.
火災危険
Behavior in Fire: Irritating fumes of hydrogen chloride given off when water or foam is used to extinguish adjacent fire.
安全性プロファイル
Poison by ingestion.
Corrosive. Mutation data reported. See
ANTIMONY COMPOUNDS and
ANTIMONYPII) CHLORIDE. When
heated to decomposition it emits very toxic
fumes of Cland Sb.
職業ばく露
It is used in dyeing, coloring metals
and in many organic chemical reactions as a catalyst.
輸送方法
UN1730 (liquid) Antimony pentachloride, liquid,
Hazard class: 8; Labels: 8-Corrosive material. UN1731
(solution) Antimony pentachloride, solutions, Hazard class:
8; Labels: 8-Corrosive material.
不和合性
Decomposes on contact with heat, acids,
alkalis, ammonia, water or other forms of moisture producing
fumes of hydrogen chloride and antimony. Decomposes
above 77 C forming chlorine and antimony trichloride.
Attacks many metals in the presence of moisture forming
explosive hydrogen gas. Reacts with air forming corrosive
vapors.
廃棄物の処理
Encapsulate and transfer to an
approve landfill. If chemically treated and neutralized, the
chemical is amenable to biological treatment at municipal
sewage treatment plant. 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.
