Diamond Hazard Value Description
1 0
Health   1 Exposure would cause irritation with only minor residual injury (e.g. acetone, sodium bromate, potassium chloride)
Flammability   2 Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur and multiple finely divided suspended solids that do not require heating before ignition can occur. Flash point between 37.8 and 93.3 °C (100 and 200 °F). (e.g. diesel fuel, sulfur)
Instability   0 Normally stable, even under fire exposure conditions, and is not reactive with water (e.g. helium,N2)

Butylbenzene Chemical Properties,Uses,Production

Chemical Properties

colourless liquid


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


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

General Description

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 Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

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.


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.

Safety Profile

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.

Purification Methods

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.]
