One of the most important components of soap made of olive oil is sodium oleate. This can also make up a significant part of tallow soap. It is composed from two parts of both the hydrophilic or hydrophobic group. It has high emulsifying powers, penetrating strength, detergency, as well its solubility when heated water. It serves as an anionic solvent and fabric waterproofing agents.
The nature and uses of sodium Oleate
1. Oxidation
The color can also be gradually oxidized, and then colored in air. This will darken it and cause rancidity. Oleic acid, which is also known as oleic acid, is destroyed by oxidation. Additionally, double bonds are formed to make dangerous substances like furfural. Corruption is encouraged by the mixing of high unsaturated acids.
2, Solubility
This solution dissolves in 10X the water. The foaming results in a viscous, clear liquid. The alkaline aqueous solution makes the liquid turbid because of partial reaction to insoluble acidic detergent and sodium hydroxide. It is not easily soluble in ethanol, and is completely neutral. About 20 times more ethanol will dissolve. Do not mix with ether, petroleum alcohol or other organic solvents.
3. Chemische Reaktion
When it is mixed with another metal ion, it forms a metal salt precipitate.
4, other properties
In most cases, it is non-volatile in nature. It can be dissociated completely into ions by adding water. Add inorganic acid to the soap liquid and it can become hydroxy acid. If the hot soap liquid is left to cool it will not crystallize. Instead, precipitates are formed of insoluble calcium/magnesium soap with calcium/magnesium salts. Property and appearance: A white powder with a density of about 0.9g/cm3. The melting point is between 232 and 235 ° C (lit. ); boiling points: 359.999oC @ 760mmHg; flashpoint at 270.099oC. This product is not compatible with strong-oxidizing agents. Keep at room temperature below 20oC
Preparation sodium oleate
It can be obtained by neutralizing either sodium hydroxide, or sodium carbonate within an oleic acid-ethanol solution.
10 g of oil can be mixed in 100mL of 95%ethanol. After that, the solution should have a sodium hydroxide concentration of at least 0.5 mg/L. After reaching the equivalence points, the precipitated sodium oil soap was filtered. It is possible to distill ethanol from water in order not to precipitate the sodium oleate soap.
Useof sodium oleate
1. It is also the main ingredient of soap made out of olive oil or other vegetable oils.
2 is used as food film. It can also be mixed with high-boron fatty alcohol, ethylene oxide or fruit, vegetable film.
3. The waterproofing and processing of mineral materials in fabrics
4 may be used as an anti-corrosion agent for aluminum alloys, iron or copper.
5. This is an anionic surfactant that can be used to waterproof fabric.
Safety in sodium oleate
Acute toxicities: LD50, half-lethal dose in mice: 152mg/kg. Rabbit LD50: 150mg/kg. Avoid taking it internally. Use it on the skin or mucous membranes. The anionic surfactant sodium oleate has is sodium oleate. Food Safety Law stipulates that this ingredient cannot appear in the Food Safety National Standard Food additive Standard GB2760 – 2011. This means sodium oleate can not be considered a food additve. It is safe to use in drinking water. But, sodium oleate cannot be released into the environment without approval from the government.
