1-ニトロオキシプロパン 化学特性,用途語,生産方法

• 用途

  液体ロケット推進薬

• 化学的特性

  n-Propyl nitrate is a colorless to pale yellow liquid. Ethereal odor.

• 物理的性質

  Colorless to light yellow, flammable liquid with an ether-like odor. Odor threshold concentration is 50 ppm (quoted, Amoore and Hautala, 1983).

• 使用

  Fuel ignition promoter, in rocket fuel formulations, as organic intermediate.

• 一般的な説明

  A white to straw-colored liquid with an ether-like odor. About the same density as water and insoluble in water. Flash point 70°F. Vapors heavier than air. Used as a fuel. Shock sensitive. The shock sensitivity is removed by addition of 1-2% of propane, butane, chloroform, ethyl ether, or methyl ether.

• 空気と水の反応

  Highly flammable. Insoluble in water.

• 反応プロフィール

  Organonitrates, such as n-Propyl nitrate, range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. Nitroalkanes are milder oxidizing agents, but still react violently with reducing agents at higher temperature and pressures. Nitroalkanes react with inorganic bases to form explosive salts. The presence of metal oxides increases the thermal sensitivity of nitroalkanes. Nitroalkanes with more than one nitro group are generally explosive. Contact with either strong oxidizers or with combustibles may cause fires and explosions.

• 危険性

  Flammable, severe fire and explosion risk, strong oxidizing material, explosive limits in air 2– 100%. Nausea and headache.

• 健康ハザード

  Exposure can cause anoxia and cyanosis. Other effects are weakness, dizziness, and severe headaches.

• 火災危険

  Special Hazards of Combustion Products: Toxic gases and vapors, such as oxides of nitrogen and carbon monoxide, may be released in a fire.

• 安全性プロファイル

  Poison by intravenous route. Inhalation can cause hypotension and methemoglobinemia. Dangerous fire hazard when exposed to heat, flame, or oxidizers. Explosive in the form of vapor when exposed to heat or flame. A shock-sensitive explosive. It can be desensitized by the addition of 1-2% propane, butane, chloroform, dunethyl ether, or dithyl ether. When heated to decomposition it emits toxic fumes of NOx. Used as a fuel ignition promoter, chemical intermediate, and in the manufacture of rocket fuels. See also NITRATES and ESTERS.

• 職業ばく露

  Propyl nitrate has been used as an intermediate as a rocket propellant and as an ignition improver in diesel fuels.

• 輸送方法

  UN1865 n-Propyl nitrate, Hazard Class: 3; Labels: 3-Flammable liquid.

• 不和合性

  Vapor may form explosive mixture with air. Reacts with reducing agents, combustible materials; may be violent. A shock-sensitive explosive. The shock sensitivity is removed by addition of 1%?2% of propane, butane, chloroform, ethyl ether, or methyl ether . May explode on heating. Forms explosive mixtures with com- bustible materials. This material is an organonitrate. They can range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides, and nitrides, they may begin a vigorous reaction that culminates in a detonation. Nitroalkanes are milder oxidizing agents, but still react violently with reducing agents at higher tem- perature and pressures. Nitroalkanes react with inorganic bases to form explosive salts. The presence of metal oxides increases the thermal sensitivity of nitroalkanes. Nitroalkanes with more than one nitro group are generally explosive. Contact with either strong oxidizers or with combustibles may cause fires and explosions .

• 廃棄物の処理

  Incineration: large quantities of material may require nitrogen oxide removal by catalytic or scrubbing processes . An alternative route suggested involves pouring over soda ash, neutralizing with HCl and flushing to the drain with water.
