| 外観 | 無色～ほとんど無色, 澄明の液体 | | 溶解性 | 水に微溶, エタノール, エーテルに易溶。水に溶ける。 | | 用途 | 合成香料、除草剤の中間体、ガスの着臭剤 | | 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 | | 化学的特性 | Propyl mercaptan has a characteristic odor of cabbage. Below 2 to 3 ppm, it has a sweet onion and cabbage-like flavor. | | 化学的特性 | Propanethiol is chemically classified among the thiols, which are organic compounds with molecular formulas and structural formulas similar to alcohols, except that sulfur-containing sulfhydryl group (- SH) replaces the oxygen - containing hydroxyl group in the molecule. Propanethiol's basic molecular formula is C3H7SH, and its structural formula is similar to that of the alcohol n-propanol. | | 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-PP can be used as a capping agent that improves the thermal stability and light absorption of silver nanoparticles (AgNPs), which can be incorporated into the perovskite solar cells. Gallium-arsenic (Ga-As) can be surface functionalized with 1-PP and can be potentially used in the fabrication of group VI precusors and self-assembled electron beam resists in semiconductor industry. It can also form a SAM on gold(111) surface that may be used to immobilize macromolecules. | | 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. | | 使用 | Chemical intermediate, herbicide. | | 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. | | 定義 | ChEBI: An alkanethiol that is propane substituted by a thiol group at position 1. | | 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. | | 燃焼性と爆発性 | Flammable | | 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.] |
