Chemische Eigenschaften
clear colorless to slightly yellowish liquid
Verwenden
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.
Vorbereitung Methode
2-Ethylbutanol can be prepared commercially by the aldol
condensation of acetaldehyde and 1-butanal and subsequent
hydrogenation.
Allgemeine Beschreibung
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.
Air & Water Reaktionen
Flammable. Slightly soluble in water.
Reaktivit?t anzeigen
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.
Hazard
Moderate fire risk.
Health Hazard
Liquid causes eye burns. Vapors may be mildly irritating to nose and throat.
Brandgefahr
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.
Sicherheitsprofil
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.
m?gliche Exposition
Used as a solvent; for making dyes,
perfumes, flavorings, and drugs
Stoffwechsel
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].
