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 food purposes fractionation resulting mixture acids and repeated recrystallization from methanol (90%) and acetone (at -40 ° C).
Technical oleic acid is widely used in the chemical, petrochemical, and refining industries light.
Oleic acid salts are the components used in the production of detergents.
The very acid is widely used in the paint industry as a plasticizer, forming part of lacquers, 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, is a component of lipid-lowering drugs.
The metal used as coolant for machining hard-of high (stainless) steel and alloys.
