1-Dodecene(CAS NO: 112-41-4)

Properties: A colorless, transparent liquid with a slight aroma. Melting point: -35°C (liquid phase), boiling point: 213-216°C (vapor phase), density: 0.758-0.80 g/mL (20°C), refractive index: 1.429-1.432 (20°C), flash point: 77-78°C (liquid phase). Soluble in alcohol, ether, acetone, and petroleum ether; insoluble in water. While chemically stable, it is flammable and incompatible with alkalis, strong oxidants, and reducing agents. The oral LD₅₀ in rats is <5000 mg/kg, indicating low toxicity.

Uses: It is an important chemical raw material, serving as a core ingredient in the production of surfactants and detergents, improving their detergency and stability. It is used to enhance the lubricity, oxidation resistance, and wear resistance of lubricants, extending the life of equipment. In the plastics industry, it is used as a plasticizer to improve the flexibility and processing properties of plastics. It is used to improve the adhesion and durability of coatings and the bond strength of adhesives. In organic synthesis, it serves as a precursor for the production of other chemical products, such as didodecene phenol.
