Uses
Pegosperse(R) 400 MO is a mid-range HLB, surface active agent suggested for use in animal feed (emulsifier), cosmetics (emulsifier), textile chemicals (emulsifier, lubricant, softener, scouring agent), coatings (emulsifier) and industrial degreasers.
Uses
Pegosperse(R) 600 MO is used as an emulsifier for personal care and water treatment and as a processing aid in textile industry.
Synthesis
Put 300.0g of oleic acid and 1.68g of catalyst (composed of tetramethyl ammonium chloride and CoO, the mass ratio of tetramethyl ammonium chloride to CoO was 1:0.25) into a 2L reactor with stirring, electric heating jacket and internal water-cooling coil, and seal the reactor. Nitrogen was replaced with nitrogen in the reactor three times, stirring was turned on, the temperature was raised to 90 at a pressure of -0.09 MPa for vacuum treatment for 60 min, then the temperature was raised to 140 and maintained at this temperature, ethylene oxide was passed through, and the reaction pressure was maintained at 0.3 MPa by controlling the rate of passage of ethylene oxide, and the passage of ethylene oxide was stopped when the total amount of ethylene oxide passed through was 373.8 g. The reaction was carried out at 140 for ripening The reaction was carried out until the pressure no longer decreased (indicating that the ripening reaction had been completed), and vacuum treatment was carried out at a pressure of -0.09 MPa for 30 min, and then the temperature was lowered to 40 C. to obtain a fatty acid polyoxyethylene ester product.
