General Description

Clear colorless liquid.

Air & Water Reactions

Highly flammable. Sensitive to moisture. May decompose on exposure to moist air. Insoluble in water.

Reactivity Profile

Epoxides, such as 1,2-Epoxydodecane, are highly reactive. They polymerize in the presence of catalysts or when heated. These polymerization reactions can be violent. Compounds in this group react with acids, bases, and oxidizing and reducing agents. They react, possibly violently with water in the presence of acid and other catalysts. 1,2-Epoxydodecane is incompatible with strong oxidizers, strong acids and strong bases. 1,2-Epoxydodecane is also incompatible with peroxides.

Fire Hazard

1,2-Epoxydodecane is combustible.

Flammability and Explosibility

Non flammable

Safety Profile

Questionable carcinogen with experimental tumorigenic data. When heated to decomposition it emits acrid smoke and irritating fumes.
