Reference Information

hydrophilic-lipophilic balance (HLB value)    15.1

preparation    a 2L reactor with stirring, electrical heating jacket and internal water-cooled coil was charged with 300.0G of oleic acid, 1.68g of catalyst (composed of tetramethylammonium chloride and CoO, the mass ratio of tetramethylammonium chloride to CoO is 1:0.25), and the reaction kettle is sealed. Replace the nitrogen in the reactor with nitrogen for three times, turn on the stirring, raise the temperature to 90 ℃, carry out vacuum treatment at the pressure of-0.09MPa for 60min, then raise the temperature to 140 ℃ and maintain the temperature, and add ethylene oxide, by controlling the feeding rate of ethylene oxide to maintain the reaction pressure of 0.3MPa, when the feeding of ethylene oxide after a total of 373.8g to stop the aging reaction at 140 °c until the pressure no longer drop (indicating that the aging reaction has been completed), and the vacuum treatment was carried out at a pressure of -0.09MPa for 30min, and then the temperature was reduced to 40 ° C., and the fatty acid polyoxyethylene Ester product was obtained.

performance and application    specification performance and application PEG400MO emulsifier, polyethylene glycol oleate dissolved in benzene, isopropanol, dispersed in water, it is used as industrial special lubricant, industrial grease removing agent, vinyl plastic Sol viscosity stabilizer, textile softener, lubricant, dry cleaning agent, oil-based cutting fluid balance emulsifier, plastic antistatic agent and dispersant. PEG400DO soluble in mineral, vegetable oil, water is dispersed, W/o emulsifier, solubilizer, kerosene emulsifier, industrial lubricants. PEG600MOPEG600DOPEG4000MOPEG6000MO1. soluble in water, with good washing, emulsifying, lubricating properties. 2. cosmetics As O/W emulsifier, textile industry as leveling agent, dispersant, softener, metal processing as lubricant. Pesticide used as pesticide emulsifier, can also be used for water-soluble coatings and printed circuit board pickling.

type    Non-ionic

Chemical composition    polyethylene glycol oleate

production method    put 1mol oleic acid and catalyst amount of potassium hydroxide into the reaction kettle, gradually raise the temperature, vacuum dehydration. After the water was removed, the air in the kettle was replaced with nitrogen. After the air was removed, ethylene oxide was introduced for ethoxylation. The reaction temperature was maintained at 180-200 ° C. And the pressure was 0. 2~0. 3MPa. After the completion of the ethylene oxide, cooling, the feed liquid into the neutralization pot with glacial acetic acid to adjust the pH value to 6. 0-7. 0. and then add hydrogen peroxide decolorization, and then cooling the output is the finished product.
