(Sorbitan monopalmitate CAS 26266-57-9)

Overview of Sorbitan MonopalmitateSorbitan monopalmitate (Sipan 40) is a chemical substance with the formula C22H42O6. Sorbitan monopalmitate (Sipan 40) is a food additive produced by the esterification reaction of palmitic acid and dehydrated sorbitol, and is often used as an emulsifier in food.Properties of Sorbitan MonopalmitateMelting Point: 46-47 ° C (lit.)Boiling Point: 444.68 ° C (rough estimate)Density: 1.0412 (rough estimate)Refractive Index: 1.4593 (estimate)Flash Point: >230 ° FStorage Conditions: Inert atmosphere, Room TemperatureSolubility: Almost insoluble in water, soluble in fatty oils, slightly soluble in alcohols.Form: SolidColor: White flakesWater Solubility: Insolubility in waterPerformance of Sorbitan MonopalmitateMilk white to light brown waxy solid with a slight fatty odor. Melting point 45 ℃. Dispersed in hot water and soluble in hot oil. Stable at room temperature in different pH values and electrolyte solutions. The HLB value is 6.7. Rat oral LD50>10g/kg, ADl0-25mg/kg (FAO/WHO, 1994).White to yellow water solid, melting point about 45-47 ℃. This product is insoluble in water, can be dissolved in polar organic solvents, can be dispersed in hot water, is a non-ionic surfactant, HLB 6.7, electromagnetic, dispersing, wetting and other properties.Production Methods of Sorbitan MonopalmitateAdd 1mol of sorbitol into the reaction vessel, vacuum and dehydrate at 75-80 ℃ until small bubbles are formed inside the vessel. Melt 1mol of palmitic acid and press it into dehydrated sorbitol anhydride. Add 1kg of 50% alkaline solution while stirring. Gradually raise the temperature to 190-200 ℃ under reduced pressure, and keep it at 190-200 ℃ for 4 hours. Sample and analyze the acid value. The esterification reaction is completed when the acid value is around 7-8. Let it stand and cool overnight, remove the bottom coking material, add an appropriate amount of hydrogen peroxide for decolorization under stirring, and finally heat up to 80-90 ℃. Stir and shape while hot, and cool the packaging to obtain the finished product.Technical Parameter of Sorbitan Monopalmitate
