Uses and synthesis of Sorbitan trioleate liquid

Sorbitan trioleate liquid is a synthetic nonionic emulsifier, Sorbitan trioleate Raw Materials is produced by partial esterification of sorbitol or sorbitan anhydride with food grade palmitic acid.Sorbitan trioleate CAS 26266-58-0 is a light creamy yellow to brownish yellow fine bead-like or hard waxy particles. Sorbitan trioleate is a light creamy yellow to brownish yellow fine beaded, flaky or hard waxy particles with a mild greasy odor and a caramel sweet taste.

Sorbitan trioleate Raw Materials-85 is not a single compound, but a mixture of similar compositions, with sorbitol-driven trioleate as the main component. It has a low viscosity, the smallest HLB value, and the strongest lipophilicity, making it an excellent water-in-oil (w/O) emulsifier, and an auxiliary emulsifier for the O/W type.

Applications / Functions of Sorbitan trioleate liquid

• Sorbitan trioleate liquid is used as emulsifier, solubilizer and antirust agent in pharmaceutical, cosmetic, textile, paint, petroleum products, oil extraction industry.
• Sorbitan trioleate CAS 26266-58-0 Used as emulsifier, lubricant, wetting agent, dispersant, thickener, etc.
• Gas chromatography stationary liquid, nonionic surfactant, water/oil emulsifier, dispersant.

Physicochemical Property of Sorbitan trioleate liquid

Sorbitan trioleate Raw Materials is amber to brown oily liquid, relative density (25℃) is 0.95±0.05, melting point 10℃, slightly soluble in isopropanol, perchloroethylene, xylene, cotton seed oil, mineral oil.

Production methodprocess of Sorbitan trioleate liquid

Put 1mol of sorbitol into the reaction kettle, vacuum dehydration, preheated refined oleic acid into the kettle, the amount of oleic acid added 3mol, and then add the appropriate amount of sodium hydroxide as a catalyst. Then the temperature was gradually increased to about 210℃ under vacuum, and the reaction was held for 8h.

Take a sample to measure the acid value of 14-15mgKOH/g esterification reaction is over. Static layering, the lower layer of liquid thrown off, the upper layer of liquid into the decolorization kettle, decolorized with hydrogen peroxide, dewatering under reduced pressure, dehydration is completed after the discharge of packaging that is Sorbitan trioleate Raw Materials .
