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
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.
