Overview of Sorbitan Monooleate
Sorbitan monooleate, also known as sorbitan monooleate, can be used as a nonionic surfactant.
Span-80 is a yellow oily liquid, easily soluble in water, ethanol, methanol or ethyl acetate, and very slightly soluble in mineral oil. It is a w/o type emulsifier, which has strong emulsification, chemical dispersion and lubrication effects. It can be mixed with various surfactants, especially suitable for Tween-60, and the effect is better when used in combination. HLB value is 4.7, melting point is 52-57℃.

Performance of Sorbitan Monooleate
Using sorbitol as raw material, dehydration and ring-closure are performed to generate sorbitol, which is then esterified with oleic acid. An amber viscous oily substance with oily properties, relative density of 1.029, and melting point of 10-12°C. It has a fat smell, is insoluble in water, can be dispersed in hot water, and is soluble in organic solvents. It is a nonionic surfactant with an HLB value of 4.3. It has emulsification, solubilization and diffusion capabilities, as well as defoaming and stabilizing effects. It is not soluble in isopropyl alcohol, tetrachlorethylene, xylene, cottonseed oil, mineral oil, etc. It is a high-grade lipophilic emulsifier.

Production Methods of Sorbitan Monooleate
Add 70% sorbitol into the stainless steel reactor, add 0.6% mass dehydration catalyst (phosphoric acid or p-toluenesulfonic acid), alcohol: acid = 1: (1.5~1.7) (molar ratio), and heat up to below 150°C , lose water for 3 hours; then add oleic acid preheated to 90% and 0.3% mass esterification catalyst (KOH or NaOH) into the dehydrated sorbitol, and raise the temperature to 210°C under nitrogen filling for 4 to 5 hours; when When the acid value is less than 8mgKOH/g, the reaction ends; the product is obtained after standing, cooling and filtering.
Put 88kg of sorbitol into the reaction kettle and dehydrate under reduced pressure. After dehydration is completed, press in 130kg of refined oleic acid and an appropriate amount of sodium hydroxide (as a catalyst). Start stirring, evacuate, slowly raise the temperature, and react at 200~210°C for 6 hours. Take a sample and measure the acid value. When the acid value is 6 to 7, the esterification reaction is completed. Cool down and let it stand for 24 hours. After letting it stand, it is divided into upper and lower layers. The lower layer is a black gelatinous substance. Separate and discard it. Pour the upper clarified liquid into the decolorizing kettle, heat it to about 65°C and decolorize with activated carbon, and decolorize at 80-85°C for 1 hour. Filter, and the filtrate is dehydrated under vacuum for 5 hours to obtain the finished product.

Application of Sorbitan Monooleate
1. Used as emulsifier, stabilizer, thickener, and wetting agent in medicine, cosmetics, and textile industries. It can also be used as dispersant in paint industry and emulsifier in oil fields.
2. Emulsion explosives, petroleum, medicine, cosmetics, textiles, paint, leather and other industries
3. Gas chromatography stationary solution, also used as emulsifier

4. W/O food emulsifier, used alone or mixed with Tween-60, Tween-80, and Tween-65. China stipulates that it can be used in vegetable protein beverages, milk, hydrogenated vegetable oil, bread, pastries and toffee, with a maximum dosage of 1.5g/kg; in fruit juice (flavored) beverages, the maximum dosage is 0.05g/kg. In addition, it can also be used for the preservation (coating) of vegetables and fruits, and can be used in appropriate amounts according to production needs.
5. Nonionic surfactants can be used to form oil-in-water emulsions, and can be combined with low HLB surfactants to form water-in-oil emulsions.
6. Good oil-in-water emulsifier. Gas chromatography stationary solution (maximum operating temperature 150°C, solvent is methanol), separates and analyzes oxygenated compounds. stabilizer. Thickening agent for food, cosmetics and drugs. Fiber lubricants and softeners for the textile industry.
