1838-19-3 - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| overview | oleylamine is a surfactant, soluble in acetone, carbon tetrachloride, chloroform, ethanol, isopropanol, kerosene, methanol, toluene and white mineral oil and other general organic solvents, insoluble in water [1.1], irritating skin, strong irritation to eyes, liquid state in summer and solid in winter, mainly used as emulsifier, dispersant, flotation agent, fungicide, release agent and softener. It can also be used in cosmetics, ceramics, dyes and pigments, lubricating cutting oil, metal processing, mineral processing, petroleum, plastics, ink, rubber, textiles, tanning, water treatment, etc. Oilamine plasticizers have good plasticizing properties, good compatibility, and can be used as cold-resistant plasticizers. Its main disadvantage is poor heat resistance and weather resistance. When storing, care should be taken to avoid contact with strong inorganic acids and strong oxidants. |
| use | this product can be used as softener and waterproof agent for chemical fibers. Can also be used as dye, coating dispersant, metal rust inhibitor. Organic intermediates and textile auxiliaries used in organic synthesis. |
| production method | 100 kg of oleic acid is put into a reaction kettle, heated and melted, and heated under stirring. when the material reaches about 180 ℃, ammonia gas is introduced. Ammonia enters the feed liquid from the bottom of the reactor through the distributor. Rapid stirring strengthens the contact between the gas phase and the liquid phase. The by-product water and ammonia of the end melon enter the recovery unit through the condenser. When the ammonia intake is 200kg, there is no water in the discharged gas phase. If there is no water in the gas, it is determined that the reaction reaches the end point. Stop the nitrogen passage. Dressing while hot, cooling and forming. Recrystallization with ethanol as solvent to obtain fine products. |
