1,7-Octadiene Chemical Properties,Usage,Production

Chemical Properties

CLEAR COLORLESS TO SLIGHTLY YELLOW LIQUID

Uses

1,7-Octadiene is used in organic synthesis. It is also used to study and assess the structure and reaction rate in olefin ring-closing metathesis of a series of simple dienes. Further, it is used in a study to investigate micropatterned surfaces prepared by plasma polymerization. It acts as a crosslinker as well as a source of ethylene in cross-enyne metathesis (CEYM)-related reactions.

Definition

ChEBI: 1,7-octadiene is an alkadiene that is octane carrying two double bonds at positions 1 and 7.

General Description

1,7-Octadiene can serve as a crosslinker and source of ethylene for a variant of Mori′s conditions in CEYM-related reactions.

Flammability and Explosibility

Highly flammable

Safety Profile

Mildly toxic by ingestion,inhalation and skin contact. A very dangerous fire hazardwhen exposed to heat or flame; can react vigorously withoxidizing materials. When heated to decomposition itemits acrid smoke and irritating fumes.
