• 説明

  Propane thiol is an organic compound with the molecular formula C₃H₈S. It belongs to the group of thiols. It is a colorless liquid with a strong, offensive odor. It is moderately toxic and is less dense than water and slightly soluble in water. It is used as a chemical intermediate and a herbicide . It is highly flammable and it gives off irritating or toxic fumes (or gases) in a fire. Heating it will cause rise in pressure with risk of bursting.

• 化学的特性

  clear colourless liquid

• 天然物の起源

  Reported found in onion (Allium cepa L.), garlic, shallot, roasted onion, raw leek, heated leek, chive, cooked chicken, beef, beer, American potato chips and durian (Durio zibethinus).

• 使用

  1-Propanethiol, is used widely in research areas. This compound has a wide range of applications including cell biology, materials science, nanoscience, self-assembled monolayers (SAMs), nanoelectronics, and contact printing. It is also used as a chemical intermediate.

• 定義

  ChEBI: An alkanethiol that is propane substituted by a thiol group at position 1.

• 製造方法

  By reacting propyl alcohol and H2S under particular conditions; from propyl alcohol or propyl disulfide and naphthalene; from n-propyl chloride and potassium hydrosulfide; also from n-propanol plus bromine plus red phosphorus in the presence of sodium sulfate.

• 一般的な説明

  A colorless liquid with a strong, offensive odor. Moderately toxic. Flash point below 0°F. Less dense than water and slightly soluble in water. Hence floats on water. Used as a chemical intermediate and a herbicide.

• 空気と水の反応

  Highly flammable. Vapors explosive when exposed to heat, flame or sparks. Slightly soluble in water.

• 反応プロフィール

  1-Propanethiol emits toxic fumes of oxides of sulfur when heated to decomposition. Reacts violently on contact with calcium hypochlorite [Chem. Eng. News, 1973, 51(26), p. 14].

• 危険性

  Highly flammable, dangerous fire risk.

• 健康ハザード

  Inhalation causes muscular weakness, convulsions, and respiratory paralysis; high concentrations may cause pulmonary irritation. Contact with liquid causes irritation of eyes and skin. Ingestion causes irritation of mouth and stomach.

• 火災危険

  Special Hazards of Combustion Products: Toxic sulfur dioxide is generated.

• 安全性プロファイル

  A poison. Moderately toxic by intraperitoneal route. Mildly toxic by inhalation. A severe eye irritant. A flammable liquid and very dangerous fire hazard when exposed to heat or flame. Explodes on contact with calcium hypochlorite. When heated to decomposition it emits toxic fumes of SOx. See also MERCAPTANS.

• 純化方法

  Purify the thiol by dissolving it in aqueous 20% NaOH, extracting with a small amount of *benzene and steam distilling until clear. After cooling, the solution is acidified slightly with 15% H2SO4, and the thiol is distilled out, dried with anhydrous CaSO4 or CaCl2, and fractionally distilled under nitrogen. [Mathias & Filho J Phys Chem 62 1427 1958.] Also purify it by liberating the mercaptan by adding dilute HCl to the residue remaining after steam distilling. After direct distillation from the flask, and separation of the water, the mercaptan is dried (Na2SO4) and distilled under nitrogen. [Beilstein 1 IV 1449.]
