Methyl oleate is a chemical compound from the group of fatty acid ester , more specifically, the ester of oleic acid .
Occurrence
Oleic acid methyl ester is one of the components of biodiesel .
Extraction and presentation
Methyl oleate is one of the products of the transesterification of triolein with methanol in the presence of potassium carbonate . It can also be obtained by esterifying oleic acid.
properties
Oleic acid methyl ester is a flammable, hardly ignitable, light-sensitive, colorless liquid with a characteristic odor, which is practically insoluble in water.
use
Oleic acid methyl ester was used to investigate the catalytic potential of molybdenum (VI) oxide / bipyridine dicarboxylate hybrid material. It is also used as a chromatographic reference standard in biochemical research and serves as an intermediate for detergents, emulsifiers, wetting agents, stabilizers, textile treatments, plasticizers for duplicating printing inks, rubber and waxes. It is also used for lubricants and lubricant additives.
