2-エチル-1-ブタノール 化学特性,用途語,生産方法

• 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。エタノール及びアセトンに極めて溶けやすく、水に溶けにくい。

• 化学的特性

  clear colorless to slightly yellowish liquid

• 使用

  It is used as a perfuming agent in cosmetics industry. 2-Ethyl-1-butanol is used for the synthesis of various pharmaceutical compounds, such as novel branched Alkyl carbamates, acting as anticonvulsant agent. It is also a solvent used for various organic synthesis, separation processes and ionic liquids, and solvent mixtures for pharmaceutical applications . It is also used to make penetrating oils, corrosion inhibitors, plasticizers, and perfumes; as cleaning agent for printed circuits; and to improve flow of paints and varnishes.

• 調製方法

  2-Ethylbutanol can be prepared commercially by the aldol condensation of acetaldehyde and 1-butanal and subsequent hydrogenation.

• 一般的な説明

  Flash point of 137°F. Less dense than water and slightly soluble in water. Vapors are heavier than air. Used as a solvent and in the manufacture of pharmaceuticals.

• 空気と水の反応

  Flammable. Slightly soluble in water.

• 反応プロフィール

  Flammable and/or toxic gases are generated by the combination of alcohols, such as 2-ETHYL-1-BUTANOL, with alkali metals, nitrides, and strong reducing agents. Alcohols react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.

• 危険性

  Moderate fire risk.

• 健康ハザード

  Liquid causes eye burns. Vapors may be mildly irritating to nose and throat.

• 火災危険

  HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.

• 安全性プロファイル

  Moderately toxic by ingestion and sktn contact. A skin and severe eye irritant. Flammable liquid when exposed to heat or flame; can react with oxidizing materials. To fight fire, use dry chemical, CO2, foam, fog. When heated to decomposition it emits acrid smoke and irritating fumes. See also ALCOHOLS.

• 職業ばく露

  Used as a solvent; for making dyes, perfumes, flavorings, and drugs

• 代謝

  Research reported that when 25 mmol (2.55 g) of 2-ethyl-1-butanol was administered by oral gavage to 3.0 kg rabbits (n = 3), 40% of the administered dose was excreted in the urine as the glucuronide within 24 h. Furthermore, Kamil et al. reported that 2-ethyl-1-butanol, 2.55 g (3.1 ml), administered by oral gavage to a rabbit, was excreted in the urine (24 h) as diethylacetylglucuronide. A small amount of methyl-n-propyl ketone was also excreted[1].

• 輸送方法

  UN2275 Ethylbutanol, Hazard Class: 3; Labels: 3-Flammable liquid

• 純化方法

  Dry it with CaSO4 for several days, filter and fractionally distil it. [Beilstein 1 IV 1725.]

• 不和合性

  May form explosive mixture with air. Incompatible with oxidizers, strong acids; caustics, isocyanates, amines, isocyanates.

• 廃棄物の処理

  Incineration by spraying or in paper packaging. Flammable solvent may be added.
