What is DIISOPROPYLBENZENE?

Chemical properties

clear colorless liquid

General Description

Clear amber liquid with a sharp, penetrating odor. A mixture of three isomers (ortho, meta, and para).

Air & Water Reactions

Insoluble in water.

Reactivity Profile

Vigorous reactions, sometimes amounting to explosions, can result from the contact between aromatic hydrocarbons, such as DIISOPROPYLBENZENE, and strong oxidizing agents. 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.

Health Hazard

Vapors and liquid are irritating to eyes, mucous membrane, and upper respiratory tract and can cause headache, narcosis and unconsciousness. Systemic effects can have a relatively long duration after exposure. Ingestion can be moderately to severely toxic. Liquid can cause defatting of skin and dermititis.

Fire Hazard

Special Hazards of Combustion Products: Vapors may travel considerable distance to an ignition source and flash back.
