Oleyl Diamine
Oil and Gas
Oleyl Diamine is an unsaturated aliphatic diamine derived from oleyl fatty acid, typically appearing as a pale yellow viscous liquid with a mild, amine-like odor. It is insoluble in water but soluble in alcohols, hydrocarbons, and other organic solvents. In the oil and gas industry, Oleyl Diamine is widely used as a corrosion inhibitor, emulsifier, and as a component in asphaltene dispersants, demulsifiers, and scale inhibitors. Its ability to adsorb strongly onto metal surfaces and form a hydrophobic film makes it particularly effective for protecting downhole equipment and pipelines from corrosion while stabilizing emulsions and improving fluid compatibility in production systems.
Water Treatment
Oleyl Diamine is a long-chain unsaturated aliphatic diamine typically derived from oleyl fatty acid, featuring a flexible 1,3-diaminopropane backbone with a mono-unsaturated hydrocarbon tail. It usually appears as a pale yellow to amber viscous liquid with a characteristic amine odor. It is insoluble in water but soluble in alcohols, glycols, and hydrocarbons. In water treatment, Oleyl Diamine is used as a corrosion inhibitor, emulsifier, and biocide enhancer in systems such as cooling towers, boilers, and closed-loop circulation systems. Its strong surface activity and ability to form hydrophobic films on metal surfaces help reduce corrosion and microbial growth, particularly in alkaline or mixed-phase environments.
