• Tetramethyllead

テトラメチル鉛(IV) 化学特性,用途語,生産方法

• 用途

  加鉛ガソリン

• 化学的特性

  Tetramethyl lead is a flammable, colourless liquid with a slightly sweet odour. Tetramethyl lead is insoluble in water but is soluble in most organic solvents, alcohol, benzene, and petroleum ether. Tetramethyl lead is incompatible with tetrachloro trifluoromethyl phosphorus, strong oxidisers, sulphuryl chloride, and potassium permanganate. Tetramethyl lead on hazardous decomposition releases toxic gases and particulates, such as lead fumes and carbon monoxide. It may cause fires and explosions. The commercial product is often dyed red, orange, or blue. Tetramethyl lead is frequently mixed with smaller amounts of ethylene dibromide, ethylene dichloride, dyes, kerosene, stabilisers, and inert substances.

• 使用

  Anti-knock motor fuel additive

• 一般的な説明

  Colorless liquid, dyed red, orange or blue. Has a slight musty odor. Used as an antiknock additive for gasolines; component of mixed alkyl leads for gasoline additives.

• 空気と水の反応

  Highly flammable.

• 反応プロフィール

  Tetramethyllead is sensitive to heat. Tetramethyllead can react with strong oxidizers.

• 危険性

  Flammable, moderate fire risk. Toxic by ingestion, inhalation, and skin absorption. Lower explosion level 1.8%. Central nervous system impairment. Questionable carcinogen.

• 健康ハザード

  Vapors are very toxic. Fatal lead poisoning may occur by ingestion, vapor inhalation or skin absorption. Several cases of acute toxicity, usually in the form of degenerative brain disease, have been described following occupational exposure.

• 火災危険

  Thermal decomposition is likely to take the form of vapors at the surface. Rapid decomposition will cause container to explode. Dangerous fire hazard when exposed to heat, flame, or oxidizers. Toxic gases are generated in fire. Avoid strong oxidizers such as sulfuryl chloride or potassium permanganate. Avoid fire, heat, physical damage, and strong oxidizers. Starts to decompose at about 212F. If confined, may explode or detonate at high temperatures. Hazardous polymerization may not occur.

• 安全性プロファイル

  Poison by ingestion, intraperitoneal, parenteral, and intravenous routes. Moderately toxic by skin contact. An experimental teratogen. Experimental reproductive effects. Lead and its compounds have dangerous central nervous system effects. A flammable liquid and very dangerous fire hazard when exposed to heat, flame, or oxidizers. Moderate explosion hazard in the form of vapor when exposed to flame. May explode when heated above 90℃. Explosive reaction with tetrachlorotrifluoromethyl phosphorane. Can react vigorously with oxidzing materials. To fight fire, use water, foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of Pb. Used as an octane enhancer for gasoline. See also LEAD COMPOUNDS.

• 職業ばく露

  Those engaged in the manufacture, distribution, and blending into gasoline of this antiknock agent for aviation gasoline.

• 発がん性

  TML was not mutagenic in a number of bacterial strains with or without metabolic activation.

• 輸送方法

  UN1649 Motor fuel antiknock mixtures, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

• 不和合性

  Highly flammable liquid; Vapors may form explosive mixture with air. Violent reaction with oxidizers, such as sulfuryl chloride or potassium permanganate; strong acids; especially nitric acid; chemically active metals. Decomposes and may explode in heat above 90C. Attacks rubber.

• 廃棄物の処理

  Controlled incineration with scrubbing for collection of lead oxides which may be recycled or landfilled. It is also possible to recover alkyl lead compounds from wastewaters (A-58) as an alternative to disposal.
