Sodium oleate Properties

Overview of Sodium Oleate
Sodium oleate, alias sodium octadecenoate, cis-9-octadecenol, oleol, cis-9-octadecenol, (Z) -octadecenol, olive alcohol, cis-9-octadeceno-1-ol, 9-octadecenol, octadecenol.The density of sodium oleate: 0.9 g/cm3; Melting point: 232-235°C(lit.); Boiling point: 359.999 ° C AT 760 mmHg; Flashpoint: 270.099 ° C; Storage condition: -20 ° C.Sodium oleate is an organic oil, chemical formula C17H33Co2Na, which is a white to yellow powder or a light yellowish-brown coarse powder or lump. It has a unique smell and taste. Is sodium oleate toxic? Skin contact is not thought to have harmful health effects. However, the material may still produce health damage following entry through wounds, lesions, or abrasions. Repeated exposure may cause skin cracking, flaking, or drying following normal handling and use.
Sodium oleate is soluble in alcohol and water. Sodium acid is the main component of olive oil and other soaps. It is also the main component of tallow soaps. It can also be made by reacting sodium hydroxide with oleic acid. Hydrophobic and hydrophilic compounds with excellent emulsification, permeability, and detergents, good solubility in hot water, used as anionic surfactants and fabric waterproofing agents.

Performance of Sodium Oleate
Sodium oleate does not disolved in ethanol and is neutral. It is soluble in about 20 times the amount of ethanol, and is almost insoluble in ether, petroleum ether and other organic solvents. It is made by imported oleic acid continuous saponification method and has excellent emulsifying power, penetrating power and detergency.

Why is Sodium Oleate Soluble in Water?
Salts, basic, such as SODIUM OLEATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydroxide ions and have a pH greater than 7.0. They react as bases to neutralize acids.
Sodium oleate in the air can slowly oxidize coloring, make the color dark, and produce rancids. This is due to the oxidation of oleic acid, which breaks the double bond to form a putrid substance, such as nonaldehyde. The incorporation of highly unsaturated acids promotes decay. Sodium oleate dissolves in 10 times as much water bubbles and forms a viscous liquid. The aqueous solution is alkaline. Due to partial hydrolysis into insoluble acid soap and sodium hydroxide, the liquid becomes opacified. There is no hydrolysis in ethanol, and it is neutral. Dissolved in about 20 times the amount of ethanol. Slightly insoluble in ether, petroleum ether, and other organic solvents.
Sodium oleate reacts with metal ions other than alkali metals to form a precipitate of metal salts.
The general properties of salt can not volatilize. Water can be completely dissociated into ions, add inorganic acid (strong acid), and make the salt hydroxyl acid-free. When the hot soap liquid is cooled, it does not crystallize, and the calcium and magnesium salts contained in the hard water will generate insoluble calcium and magnesium soap precipitation.

Production Methods of Sodium Oleate
Sodium oleate is obtained by neutralizing sodium hydroxide or sodium carbonate in an ethanolic solution of oleic acid.
10g of oleic acid can be dissolved in 100 95% ethanol and then titrated with 0.5mol/L of sodium hydroxide ethanol solution, using phenolphthalein as an indicator. After reaching the equivalence point, the precipitated sodium oleate soap is filtered out. If precipitation is not precipitated, crude products can be obtained after the evaporation of ethanol and water and recrystallized with ethanol-diethyl ether mixed solvent.

Application of Sodium Oleate
Sodium oleate is one of soap's main ingredients and can be used as an emulsifier. Sodium oleate is used in medicine. It is used in the treatment of cholelithiasis. In various oil-based cosmetics, sodium oleate is used as a cleaning agent, emulsifier, surfactant, thickening or gelling agent, and viscosity control agent. Examples of sodium oleate are as follows:

1. Main ingredient in soaps made from things like olive oil, as well as tallow soaps.
2. Food coating agent, such as fruit and vegetable surface coating, and can be used with ethylene oxide and high boron fatty alcohol.
3. In neutral or acidic solutions, sodium oleate can be used as a corrosion inhibitor for aluminum and its alloys, iron, copper, and other metals.
4. Anionic surfactant and fabric waterproofing agent.
5. In medicine. It is used in the treatment of cholelithiasis.
6. In various oil-based cosmetics, sodium oleate is used as a cleaning agent, emulsifier, surfactant, thickening or gelling agent, and viscosity control agent.
7. Produce insoluble metallic stearates and industrial lubricants.
8. Water-repellent agent for textiles.
9. Anionic surfactant.
10. Flotation agent for mining.
11. Laboratory reagent in producing chemicals and other oleates.
