Overview
1-Hydroxyethyl-2-Oleyl Imidazoline (OEM) is a nitrogen-containing heterocyclic compound derived from oleic acid and hydroxyethyl ethylenediamine. It is widely recognized for its dual functionality as a corrosion inhibitor and surfactant. The compound is particularly valued in industries such as oil and gas, metalworking, and personal care for its ability to form protective films on metal surfaces and stabilize emulsions. OEM is synthesized through a condensation reaction, resulting in a product that is both environmentally friendly and effective under various conditions. Its versatility and relatively low toxicity make it a preferred choice for applications requiring sustainable chemical solutions.
Physical and Chemical Properties
1-Hydroxyethyl-2-Oleyl Imidazoline is a viscous liquid with a yellow to amber appearance. It has a molecular weight of 364.61 g/mol and a density of approximately 0.92 g/cm³. The compound is soluble in most organic solvents, such as ethanol and acetone, but only slightly soluble in water, which limits its use in purely aqueous systems. Key chemical properties include its amphiphilic nature, which allows it to act as both a surfactant and a corrosion inhibitor. The imidazoline ring provides chelating properties, enhancing its ability to bind to metal surfaces and form protective layers. These characteristics are critical for its performance in industrial applications.
Main Applications
OEM is extensively used in the oil and gas industry as a corrosion inhibitor for pipelines and drilling equipment. Its ability to adsorb onto metal surfaces forms a barrier against corrosive agents like CO2 and H2S. In metalworking fluids, it serves as an emulsifier, improving the stability of oil-water mixtures and reducing friction during machining processes. The compound also finds applications in coatings and paints, where it enhances adhesion and provides anti-corrosive properties. In personal care products, OEM acts as a mild surfactant, making it suitable for shampoos and conditioners. Its multifunctionality and compatibility with other chemicals contribute to its widespread industrial use.
Safety and Storage
While 1-Hydroxyethyl-2-Oleyl Imidazoline is considered low in toxicity, proper handling is essential to avoid health risks. Direct contact with skin or eyes can cause irritation, and inhalation of vapors should be avoided. Personal protective equipment (PPE), including gloves and goggles, is recommended during handling. Storage conditions should prioritize cool, dry environments away from direct sunlight and oxidizing agents. Containers must be tightly sealed to prevent moisture absorption and contamination. In case of spills, absorb with inert material and dispose of according to local regulations. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety guidelines.
B2B Procurement Guide
When procuring 1-Hydroxyethyl-2-Oleyl Imidazoline, B2B buyers should prioritize suppliers with verified certifications, such as ISO or REACH compliance. Purity levels typically range from 90% to 98%, with higher purity grades commanding premium prices. Bulk purchases (e.g., drum or tanker quantities) often yield cost savings, but ensure storage capacity aligns with usage rates. Request samples for quality testing, particularly for critical applications like oilfield chemicals. Confirm logistics options, as OEM is classified as a non-hazardous material for transport in most regions. Long-term supplier relationships can provide stability in pricing and availability, especially given fluctuating raw material costs.
