Oleic acid - is a colorless, odorless, viscous liquid and taste, not mixable with water, dissolved in chloroform and benzene, is mixed with methanol, ethanol, diethyl ether. It is a mono-unsaturated aliphatic fatty acid, belongs to the group of omega-9 acid.
Acid intended for industrial purposes (Technical olein) is a mixture of oleic acid and some other acids, with the admixture of unsaponifiables and some other organic compounds. Is pasty substance from yellow to dark brown, the air oxidizes and darkens quickly.
The density of 0.895 g / cm³. The melting temperature of 16,3 ° C.
Chemical formula: C 18 H 34 O 2
Contained in many animal fats as esters - glycerides (olein) and in a large number of vegetable fats and oils.
Technical oleic acid is obtained by hydrolysis of various vegetable oils (soybean, rapeseed, sunflower, mustard) unsuitable for human consumption by fractionating the resulting mixture with acids, and repeated recrystallization from methanol (90%) and acetone (at -40 ° C).
Technical oleic acid is widely used in chemical, petrochemical, oil refining and light industries.
oleic acid salt components are used in the production of detergents.
The very acid is widely used in the paint industry as a plasticizer, forming part of varnishes, flotation reagents. emulsifiers and varnishes. Esters contained in oleic acid are used in the production of pulp.
Modern food industry uses flavors that are based on oleic acid.
In medicine, oleic acid is used as solvent, hormones and vitamins, it is a component of lipid-lowering drugs.
The metallurgy is used as a coolant for machining difficult-to-high-alloy (stainless) steel and alloys.
