Oleic acid structural formula: the structural short formula is CH3(CH2)7CH=CH(CH2)7COOH, that is, C17H33COOH.
A. Oleic acid
Oleic acid is a monounsaturated Omega-9 fatty acid found in the plants and animals in the body. Chemical formula C18H34O2 (or CH3 (CH2) 7CH = CH (CH2) 7COOH). Hydrogenation of oleic acid yields stearic acid. The double-bonded trans isomer of oleic acid is called trans-oleic acid. The English name "oleicacid" is derived from "olive".
Oleic acid, as a monounsaturated fatty acid, plays an important role in the composition of our body's adipose tissue, and is known as a "safe fatty acid" by the nutritional community, and edible oils are an important source of oleic acid for the human body to consume.
Two, oleic acid use
1, mainly used in the preparation of plastic plasticizer epoxy oleic acid butyl ester and epoxy oleic acid octyl ester. Wool spinning industry for the preparation of antistatic agents and lubricating softeners. Timber industry for the preparation of anti-water agent paraffin emulsion. Oxidized to prepare azelaic acid, azelaic acid is the raw material for polyamide resin. Also used in the manufacture of pesticide emulsifiers, printing and dyeing auxiliaries, industrial solvents, mineral flotation agents and mold release agents. Can also be used as the preparation of copy paper, typing paper, ballpoint pen oil and various oleates.
2, can be used as drilling mud lubrication decarburizer. Sodium or potassium salt of oleic acid is one of the components of soap. Pure sodium oleate has good decontamination ability, can be used as emulsifiers and other surfactants, and can be used to treat cholelithiasis. Other metal salts of oleic acid are also used in waterproofing fabrics, lubricants, polishes, etc. Its barium salt is used as a rodenticide.
3, used for biochemical analysis and gas chromatography standards.
4, used in the preparation of plastic plasticizers, pesticide emulsifiers, lubricants, ointments, ore flotation agent.
5, used as detergents, fatty acid soap substrate, cosmetics, chemical fiber oil, textile additives raw materials. Refined oleic acid is used as raw material for plastics, engineering plastics, nylon 8 and nylon 9.
6, used in baked goods, meat products, seasonings.
