Sodium oleate
, alias sodium octadecenoate, cis-9-octadecenol, oleyl alcohol, cis-9-octadecenol, (Z)-octadecenol, olive oil, cis -9-octadecen-1-ol, 9-n-octadecenol, octadecenol. It’s an organic oil whose chemical formula is C17H33CO2Na. It is the main constituent of olive oil soap and tallow soap. You can also make it by reacting oleic and sodium hydroxide. Composed of a hydrophobic and a hybrid base. It has good emulsification properties, excellent penetration and detergency and is easily soluble in hot water. It’s used as a surfactant anionic and fabric waterproofing.
Basic Information on Sodium Oleate
English name: SODIUM OLEATE
Oleic Acid Salt (cis-Oleate)
CAS Number: 143-291
Formula molecular: C18H33NaO2
Weight in Molecular Mass: 304.44300
Accurate quality: 304.23800
PSA: 40.13000
LogP: 4.77380
The properties of sodium oleate
Oxidizing
This can cause rancidity and cause the color to darken and oxidize. It is due to the fact that oleic is oxidized. The double bond is broken, resulting in rancid substances such as nonanal. The corruption is accelerated by mixing in highly unsaturated chemicals.
Solubility
Dissolved in 10 times more water will foam and produce a viscous solution. The aqueous solutions is alkaline. Liquid becomes milky because of partial hydrolysis to insoluble acidic soap and sodium hydroxide. It is not hydrolyzed in ethanol. In about 20x the amount of ethanol, it dissolves. It is nearly insoluble in petroleum ether and other organic solvants.
Hy-drolysis reaction: 2RCOONa+H2O=RCOONa*RCOOH+NaOH
Chemical Reaction
Reacts with other metal ions than alkali elements to produce metal salt precipitation.
Other properties
It is the nature of salt that it can’t be volatilized but can be completely dissociated in water into ions. The salt can be converted to hydroxy acid by adding mineral acids (strong acids). If the hot liquid soap is allowed to cool, it will not crystallize. It will instead form insoluble calcium-magnesium soap precipitates along with the calcium-magnesium salts found in hard water. The white powder has a density of 0.9g/cm3, a melting point between 232 and 235degC, and resembles a fine powder. The boiling point is 359.999oC when diluted to 760mmHg. The flashpoint is 270.099oC. Incompatible to strong oxidizing agents. Storage conditions: -20oC.
Sodium oleate preparation
This is made by neutralizing sodium hydroxide in a solution of oleic acids and ethanol.
Use phenolphthalein, an indicator, to titrate 10g of oleic in 100mL 95% ethanol. Once the equivalence is reached, the precipitated product can be diluted with 95% ethanol. sodium Oleate Filter out the soap. The crude product, which is obtained after the water and ethanol are distilled, can also be used if precipitation does not occur.
Use of sodium oleate
1. Olive oil soap also contains tallow as its main ingredient.
2. Use as a food coating agents, for example, to coat the surface of fruits and vegetables. Can be combined with ethylene dioxide and high-boron fatty acids.
3. Mineral processing waterproof fabric
4. This product can be used in neutral and acidic solutions to prevent corrosion on aluminum and its alloys as well as iron, copper and many other metals.
5. As an anionic surfactant, it is also used as a fabric waterproofing agent.
