Properties:
Colorless or light yellow to red oily liquid with lard like aroma and taste. After exposure to air can be gradually oxidized and dark, strong heating in the air can lead to decomposition, almost insoluble in water, mixed in ethanol, ether, benzene and volatile and non-volatile oils. Oleic acid, together with other fatty acids, exists in all animal and plant oils in the form of glycerides. When oleic acid, it is isomerized into trans-isomer. The melting point of oleic acid is 44 ~ 45ºC. Hydrogenation leads to stearic acid; A mixture of azelaic and n-azelaic acids is obtained by oxidation. Because oleic acid contains double bonds, when it is placed in the air for a long time, it can undergo autoxidation and locally transform into carbonyl substances. There is a rotten taste, which is the reason for the deterioration of the oil. Commercial oleic acid generally contains 7% to 12% saturated fatty acids.
Can be used as drilling mud lubrication release agent. Sodium salt or potassium salt of oleic acid is one of the ingredients of soap. Pure sodium oleate has good decontamination ability, can be used as surfactant such as emulsifier, and can be used to treat cholelithiasis. Other metal salts of oleic acid can also be used for waterproof fabrics, lubricants, polishes, etc. Barium salts can be used as rodenticides.
