1,9-Decadiene(CAS#1647-16-1)
Brief introduction
1,9-decadiene is a colorless liquid with a specific odor. It is a linear olefin with two carbon-carbon double bonds.
1,9-Degadiene is primarily used as a solvent and is widely used in chemical laboratories. It can dissolve many organic compounds, especially those that are more hydrophobic. It is also used in the preparation of advanced synthetic oils, high-energy fuels, and polymer materials, among others.
There are several ways to prepare 1,9-decadiene. A common method is obtained by dehydrogenation of hydrocarbons, such as octanol.
It is a flammable liquid with a low flash point and spontaneous ignition point, prone to flames and explosions. Contact with open flames, heat sources, and oxygen should be avoided. Avoid inhalation, ingestion, or skin contact as it can be toxic to humans. Appropriate personal protective equipment such as gloves, goggles, and protective clothing should be worn when handling. It should be stored in a cool, well-ventilated place away from fire and oxygen. If there is a leak, it should be properly cleaned up and disposed of immediately to avoid danger.
Application
1,9-Decadiene (CAS 1647-16-1) is a linear α,ω-diolefin with two terminal vinyl groups, valued as a versatile building block in polymer chemistry and organic synthesis. Its high purity and reactivity enable its use as a crosslinking monomer in ethylene-propylene-diene (EPDM) elastomers, introducing unsaturated cure sites that improve mechanical strength, heat resistance, and compression set. It also serves as a chain extender and branching agent for polyethylene, polypropylene, and specialty polyolefins, modifying melt flow and processability. In silicone rubber formulations, 1,9-decadiene acts as a grafting agent. As a reagent in organic synthesis, it undergoes ring-closing metathesis (RCM) to form macrocyclic compounds, as well as hydroboration, epoxidation, and thiol-ene click reactions. This diene is also used to produce long-chain diacids, diamines, lubricant intermediates, and specialty surfactants. Its excellent thermal stability and low volatility make it suitable for high-temperature applications.
