| shape | castor oil polyoxyethylene ether is a yellow viscous liquid, resistant to hard water, acid, alkali and inorganic salts. Used to emulsify and dissolve oil and other water-insoluble substances. Non-ionic solubilizer. Solubilizers and emulsifiers for water-insoluble drugs or other fat-soluble drugs used in semi-solid and liquid formulations |
| emulsifier | castor oil polyoxyethylene ether is also known as emulsifier EL-40, and the corresponding foreign brand name is Emulphor EL -620. It is a non-ionic surfactant. Light yellow transparent viscous liquid. Soluble in water, but also soluble in oils, fatty acids and a variety of organic solvents, the solubility in cold water than in hot water, mineral oil has good emulsifying properties. 1% aqueous solution pH = 6~8. HLB value 13. 1% aqueous solution of cloud point is greater than or equal to 85 deg C. Acid, hard water and inorganic salts, low temperature is also resistant to alkali, but strong alkali can make its hydrolysis. castor oil polyoxyethylene ether can be prepared by reacting castor oil with ethylene oxide under the catalysis of sodium hydroxide (or potassium). it is suitable for the emulsification of various vegetable oils, mineral oils, fats, waxes, etc. It can also be used as a component of an antistatic spinning finish for synthetic fibers such as polyacrylonitrile, a pesticide emulsifier, and a component of a wool thinning agent “and a wool oil. |
| Use | pesticide emulsifier, textile chemical fiber oil agent, oilfield crude oil dehydration. The textile industry is used as chemical fiber oil, the wool textile industry is used as wool oil, and the anti-static spinning oil of vinylon. Can also be used for oil wax, oleic acid and mineral oil emulsification. biochemical studies; Used to emulsify and dissolve oil and other water-insoluble substances. Non-ionic solubilizer. Solubilizers and emulsifiers for water-insoluble drugs or other fat-soluble drugs used in semi-solid and liquid formulations |
| production method | 1 mol of castor oil was added to the reaction kettle, followed by addition of 0.3% solid potassium hydroxide, equivalent to the mass of castor oil. The mixture was stirred and the temperature was raised until the KOH was dissolved. The air in the kettle was then replaced with N2. The reaction temperature was maintained at 160-180 ° C. And the pressure was 0.15-0.2 MPa. After the passage, the stirring was continued until the pressure did not drop. Cooling. The material was transferred into the bleaching kettle, the pH was adjusted to slightly acidic with acetic acid, decolorized with 0.1% hydrogen peroxide, and incubated at 70 °c for 0.5 h. The final decompression dehydration 5 h. The discharge was cooled. The reaction scheme is as follows. obtained by condensation, neutralization and decolorization of castor oil and ethylene oxide (see castor oil polyoxyethylene [90] ether for details). 04395). |
