What is 1,7-Octadiene?
Chemical properties
CLEAR COLORLESS TO SLIGHTLY YELLOW LIQUID
The Uses of 1,7-Octadiene
1,7-Octadiene has been used in a study to assess the structure and reaction rate in olefin ring-closing metathesis of a series of simple dienes. It has also been used in a study to investigate micropatterned surfaces prepared by plasma polymerization.
The Uses of 1,7-Octadiene
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.
