What is OCTAFLUORO-2-BUTENE?

General Description

A colorless, nonflammable gas. May asphyxiate by the displacement of air. Under prolonged exposure to fire or heat the containers may rupture violently and rocket. Used to make other chemicals.

Reactivity Profile

OCTAFLUORO-2-BUTENE may be incompatible with strong oxidizing and reducing agents. Also may be incompatible with many amines, nitrides, azo/diazo compounds, alkali metals, and epoxides.

Health Hazard

Vapors may cause dizziness or asphyxiation without warning. Vapors from liquefied gas are initially heavier than air and spread along ground. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating, corrosive and/or toxic gases.

Fire Hazard

Some may burn but none ignite readily. Containers may explode when heated. Ruptured cylinders may rocket.

Safety Profile

Mildly toxic by inhalation.Mutation data reported. When heated to decomposition itemits toxic fumes of Fí.
