Oleic acid is a monounsaturated Omega-9 fatty acid that exists in animals and plants. Pure oleic acid is a colorless oily liquid with the smell of animal oil or vegetable oil. The color gradually becomes darker after being left in the air for a long time. Industrial products are yellow to red oily liquid with the smell of lard. The melting point is 16.3°C, the boiling point is 286°C (100 mmHg), the relative density is 0.8935 (20/4°C), the refractive index is 1.4582, and the flash point is 372°C. Easily soluble in ethanol, ether, chloroform and other organic solvents, but insoluble in water. Flammable. It is easily saponified when exposed to alkali and forms a white soft solid after solidification. Easily oxidized, polymerized or decomposed under high heat. Non-toxic.
Oleic acid has the following uses:
The lead salt, manganese salt, and cobalt salt of oleic acid are paint driers; the copper salt is used for anti-corrosion of fishing nets. Agent; aluminum salt can be used as fabric waterproofing agent and thickener of some lubricating oils.
Other metal salts of oleic acid can also be used in waterproof fabrics, lubricants, polishes, etc. Its barium salt can be used as a rodenticide.
Oleic acid can be epoxidized to produce epoxy oleate (plasticizer). Azelaic acid (raw material for polyamide resin) is produced through oxidative cracking.
Used in the wool spinning industry to prepare antistatic agents and lubricating softeners.
Used in the wood industry to prepare water-repellent paraffin emulsion.
As a chemical reagent, used as a chromatographic comparison sample and in biochemical research, it can be used to determine calcium, ammonia, copper, and determine magnesium, sulfur, etc. Activation of protein kinases in hepatocytes.
It can also be used as pesticide emulsifier, lubricant, printing and dyeing auxiliary, industrial solvent, metal mineral flotation agent, release agent, grease hydrolyzing agent, and used to prepare copy paper, typing paper, ballpoint pen oil and Various oleates, etc.
A 75% alcohol solution of oleic acid can be used as a rust remover.
