Chemische Eigenschaften
colourless liquid
Physikalische Eigenschaften
Clear, colorless, liquid with a faint petroleum or gasoline-like odor similar to that of npropylbenzene.
Nagata and Takeuchi (1990) reported an odor threshold concentration 8.5 ppb
v.
Verwenden
Butylbenzene is used in the preparation of butyl-silica hybrid monolithic column.
Definition
ChEBI: An alkylbenzene that is benzene substituted by a butyl group at position 1.
Allgemeine Beschreibung
A colorless liquid. Less dense than water and insoluble in water. Flash point between 75 - 140°F. Used to make plastics and as a solvent.
Air & Water Reaktionen
Highly flammable. Insoluble in water.
Reaktivität anzeigen
Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as BUTYL BENZENE, and strong oxidizing agents. They can react exothermically with bases and with diazo compounds. Substitution at the benzene nucleus occurs by halogenation (acid catalyst), nitration, sulfonation, and the Friedel-Crafts reaction.
Hazard
Toxic by ingestion.
Health Hazard
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control or dilution water may cause pollution.
Sicherheitsprofil
Mildly toxic by
ingestion. Flammable when exposed to heat
or flame. To fight fire, use alcohol foam,
CO2, dry chemical. Incompatible with
oxidizing materials. When heated to
decomposition it emits acrid and irritating
fumes.
läuterung methode
Distil butylbenzene from sodium. Wash it with small portions of conc H2SO4 until the acid is no longer coloured, then with water and aqueous Na2CO3. Dry it ( MgSO4), and distil it twice from Na, collecting the middle fraction [Vogel J Chem Soc 607 1948]. [Beilstein 5 IV 1033.]
