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’s composed of two portions of the hydrophilic as well as hydrophobic groups. It has high emulsifying powers, penetrating strength, and detergency. Also, it is well-soluble in hotwater. It serves as an anionic solvent and fabric waterproofing agents.
The nature and uses of sodium Oleate
The color can also be gradually oxidized, and then colored in the open 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.
This solution dissolves in 10x more 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 insoluble with ethanol, and is 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
The nature of salt is invariably stable. It can be easily dissociated from water to form ions. 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 magnesium soap with calcium, magnesium, and hard water. Property and appearance: A white powder with a density of about 0.9 g/cm3, melting point at 232-235°C (lit. ); melting point: 232-235 ° C (lit. This product is not compatible with strong-oxidizing agents. Conditions of storage: Storage at -20oC
Preparation sodium oleate
It can be obtained by neutralizing either sodium hydroxide, or sodium carbonate within an oleic acid-ethanol solution.
10g of oleic Acid can be mixed in 100mL of 95%ethanol. After that, the solution should have a sodium hydroxide concentration of at least 0.5mol/L. After reaching the equivalence points, the precipitated sodium oil soap was filtered. It is possible to distill ethanol from water and obtain the raw product.
Uses sodium oleate
1. It is also the main ingredient in soap made from olive oils, etc.
2 used in food films like fruit, vegetable skin film.
3. The waterproofing and processing of mineral materials in fabrics
4 may be used as an anti-corrosion agent for aluminum and its alloys. It also works well with iron, copper and other metallic materials in neutral or acidic environments.
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, is also known as sodium oleate. Food Safety Law stipulates that this ingredient cannot appear in the Food Safety National Standard Food additive Standard GB2760 – 2011. This is to say, 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.
