Molecular Formula:C22H42O6.(C2H4O)n
Specification:500ml
Description:Polyoxyethylene sorbitan monopalmitate for amber oily liquid, relative density 1.05 ~ 1.10, the refractive index of 1.470, 0.4 ~ 0.6 Pa s. viscosity (25 ℃), the HLB value of 15.6. Soluble in water, dilute acid, dilute alkali and most organic solvents, insoluble in vegetable oil and mineral oil.
Polyoxyethylene sorbitan monopalmitate production methods: 1 mol, 40, plate into the reaction kettle, after heated to melt, stir in 50% sodium hydroxide as catalyst, vacuum, vacuum dehydration, dehydration after using nitrogen replacement cauldron in air, the air displacement net access after 20 mol, epoxy ethane in esterification reaction, esterification temperature at 160 ~ 180 ℃, pressure is 0.2 ~ 0.3 MPa. After epoxy ethane is passed, it is cooled to about 90℃, and the acid value is adjusted by glacial acetic acid to 1.5 ~ 2 mgKOH/g for neutralization. Finally, it is decolorized with hydrogen peroxide, and the finished product is cooled, released and packaged.
Chemical property:Amber oily liquid.
Use:Used as solubilizer,dispersing agent,anlistatig and stabilizing agent.
