DIISOBUTYLENE Chemical Properties,Uses,Production

Chemical Properties

Colorless liquid

General Description

A clear colorless liquid with a petroleum-like odor. Flash point 10°F. Less dense than water and insoluble in water. Vapors heavier than air. Used in the manufacture of other chemicals.

Air & Water Reactions

Highly flammable. Insoluble in water.

Reactivity Profile

DIISOBUTYLENE may react vigorously with strong oxidizing agents. May react exothermically with reducing agents to release hydrogen gas.

Health Hazard

Low general toxicity; may act as simple asphyxiant in high vapor concentrations.
