Use | oleyl alcohol is an unsaturated fatty alcohol that can be used as a nonionic surfactant in skin creams, lotions, and many other cosmetics, emulsifiers, emollients, and thickeners. used in the manufacture of detergents, wetting agents, defoamers, metal-cutting lubricants, plasticizers, and slip-softeners for fabrics. used in the manufacture of detergents, wetting agents, defoamers, metal-cutting lubricants, plasticizers, and slip-softeners for fabrics. It is also used as a raw material for organic synthesis and special surfactants, and can be used for the production of oil additives, cold resistant auxiliary plasticizers, lubricants and solvents. organic synthesis, biochemical research, detergent, wetting agent, Defoamer, plasticizer.; Cis-9-octenol |
production method | ethyl oleate and anhydrous acetic acid were mixed, and sodium metal tablets were rapidly added, and the reaction proceeded vigorously. After the reaction was relieved, anhydrous ethanol was added and heated to metal sodium to complete the reaction. The unreacted ethyl oleate was then saponified by refluxing with water for 1H. After cooling, it was extracted with ether, neutralized, washed and dried, and then distilled off with ether, and fractionated under reduced pressure under drought. The fraction of 150-152 ° C. (0.133kPa) was collected as oleyl alcohol. The yield was about 50%. |
