Oleic acid
Chemical the formula C17H33COOH
Density: 0,895 (18°C, g/cm3)
Reg. room CAS no.: 112-80-1
Oleic acid (CIS-9-octadecenoate acid) CH3(CH2)7СН=CH(CH2)7СООН — monounsaturated fatty acid. Belongs to the group of omega-9 unsaturated fatty acids.
Buttery liquid, lighter than water, odorless, without color, insoluble in water, but soluble in organic solvents.
Oxidized in tough conditions with potassium permanganate with the splitting of the double bond, forming a mixture of azelaic and pelargoniums acids under mild conditions in the oxidation permanganate, a mixture of stereoisomeric diocletianic acids. When the action of ozone oleic acid ozonide forms are hydrolyzed with education pelargonate aldehyde and paraldehyde azelaic acid. Hereroense to stearic acid.
Salt alkali metals oleic acid are water soluble and are used in textile industry (oleic soap). Lead salt of oleic acid, in contrast to the lead salts of the saturated fatty acids, soluble in ether, this difference in solubility based method for isolating oleic acid from of the mixture of acids obtained by saponification of natural fats.
Double bond in oleic acid has a CIS-configuration, the isomerization to TRANS-isomer — alaudinova acid occurs under the action of various catalysts (dioxide nitrogen, aliphatic NITRILES). Isomerization of oleic acid under the action of nitrous acid in a more high-melting (melting point 44 °C) alaudinova acid (elaidic test) is used to identify the type vegetable oils: a mixture of acids derived from non-drying oils containing mostly esters of oleic acid, under the influence of acidic nitrite solution sodium at room temperature solidifies into a dense mass, a mixture of acids, obtained by saponification of non-drying oils containing significant amounts polyunsaturated acids (linoleic and linolenic) in the context of alaudinova samples remains liquid.
Contains in many animal fats in the form of esters - glycerides (olein) and a large amount of vegetable fats and oils.
Technical oleic acid is obtained by hydrolysis of various vegetable oils (soy, rapeseed, sunflower, mustard) unfit for food purposes with fractionation of the resulting mixture of acids and multiple recrystallization from methanol (90%) or acetone (-40° C).
Technical oleic acid is widely used in chemical, petrochemical, oil-refining and light industries.
Salt oleic acid are the components used in the production process detergents.
The acid widely used in the paint industry as a plasticizer, as part paints, flotation reagents. emulsifiers and drying oils. Esters contained in oleic acid, used in the production of cellulose.
Modern the food industry uses flavourings that are created on the basis of oleic acids.
In medicine oleic acid is used as solvent of hormones and vitamins is a component of lipid-lowering drugs.
In metallurgy is used as a coolant in machining difficult to machine high alloy (stainless) steels and alloys.
Oleic acid and its esters are used to produce paintwork materials, as the plasticizers. Used in soap, oleic acid and its salts widely used as emulsifiers, in particular, in the composition cutting fluids) in the processing of metals by cutting is honing, broaching, deployment, etc. Also used in as the stabilizer of magnetic fluids based on hydrocarbon carriers the ferromagnetic particles.
In the production of the sizing means (for chemical fiber), flotation reagents, synthetic rubber, antifoaming agent, penetrating agent for dyeing of disperse dyes, plasticizers. Included in the cosmetic composition. Included in the composition of the olein.
Technical oleic acid is poured into railway tanks, railway tank with special heater into tank. The fill factor tanks shall not exceed 0.9. Permitted when shipping small parties packaging oleic acid in a steel or aluminum barrels with a capacity of 200 and 275 dm3. Net weight of oleic acid in barrels for more than 250 kg. Containers used for the packaging of oleic acid must be dry and clean, without foreign smell.
Technical oleic acid is a combustible product, refers to the 4th class of dangerous connections. Technical oleic acid transporterowych all kinds transport in covered vehicles in accordance with the rules of transportation of goods, operating on transport of the relevant species, and perhaps more full use of the capacity of transport. Allowed transportation oleic acid transport in open vehicles with mandatory shelter of the barrels with a clean tarp or other materials protecting them from atmospheric precipitation.
Oleic acid should be stored separately according to the types at temperatures above 50°C, tanks lined with acid resistant tiles or manufactured from materials resistant to fatty acids. The containers must be equipped with caps and coils for heating. Oleic acid in barrels should be stored in closed - ventilated areas.
