put 1 mol octylphenol into the reaction kettle, strengthen alkali as catalyst, add solid alkali equivalent to the 0.2% of octylphenol, and heat and melt. The air in the kettle was replaced with nitrogen, and after the air was removed, the temperature was raised and ethylene oxide was passed. The reaction temperature was controlled at about 180 ℃ and the pressure was 0.5 MPa. When ethylene oxide is passed to 30 mol, the cloud point of 1% aqueous solution is measured to 100~115 ℃, and the reaction is completed. The feed liquid is driven into the neutralization kettle, the pH value is adjusted to 5~7 with glacial acetic acid, and then decolorized with activated carbon. After filtration, discharge and fill the finished product.
