Chemical Description

  • Oleic acid is an unsaturated fatty acid that contains a carbon-carbon double bond. It is found in many natural sources, such as olive oil, palm oil, and lard. Oleic acid can also be produced through the hydrolysis of oil lipids.
  • It is an important nutrient in animal food and has various industrial applications, including paint driers, fishnet preservatives, and plasticizers. Oleic acid can also be used to produce epoxy oleate and azelaic acid.
  • The alkali metal salt of oleic acid is a main component of soap.
  • Most natural oleic acids have a cis-isomer structure, while trans-isomers are not absorbed by the human body.
  • Consuming edible oil that is high in oleic acid content is considered healthy.
  • Oleic acid is a single unsaturated carboxylic acid widely found in animal and vegetable oils.
  • It has two types: stable (α-type) and unstable (β-type). It appears as a colorless transparent oily liquid with a lard odor. It is insoluble in water, soluble in benzene and chloroform, and miscible with methanol, ethanol, ether, and carbon tetrachloride.
  • It easily undergoes air oxidation, producing a bad smell with the color turning yellow. It can be converted to elaidic acid with nitrogen oxides, nitric acid, mercurous nitrate, and sulfurous acid, and into stearic acid upon hydrogenation.
  • It can be obtained through the hydrolysis of olive oil and lard oil, followed by steam distillation and crystallization or extraction for separation.
  • It is an excellent solvent for other oils, fatty acids, and oil-soluble substances, and can be used for the manufacture of soap, lubricants, and flotation agents, such as ointment and oleate.
  • Oleic acid, defined as a processing aid in GB 2760-96, has multiple uses. It can act as an antifoaming agent, fragrance, binder, and lubricant. It is useful for manufacturing soap, ointments, and flotation agents.
  • It is an excellent solvent for fatty acids and oil-soluble substances. Additionally, oleic acid can be used to polish gold, silver, and other precious metals.
  • It is also a key raw material for producing epoxidized oleic acid ester, plasticizers, and azelaic acid.
  • Oleic acid is also used as a printing and dyeing auxiliary, industrial solvent, and in the sugar processing industry.
  • It is a chemical reagent used for biochemical research and can activate protein kinase C in liver cells.
  • Oleate products are important derivatives of oleic acid and it is widely used in various industries.
