N-бутилбензол

Химические свойства

colourless liquid

Физические свойства

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.

Использование

Butylbenzene is used in the preparation of butyl-silica hybrid monolithic column.

Определение

ChEBI: An alkylbenzene that is benzene substituted by a butyl group at position 1.

Общее описание

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.

Реакции воздуха и воды

Highly flammable. Insoluble in water.

Профиль реактивности

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.

Опасность

Toxic by ingestion.

Угроза здоровью

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.

Профиль безопасности

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.

Методы очистки

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.]
