put 1 mol C8 ~ 9 alkylphenol into the reaction kettle, strengthen the alkali (the amount of alkali added is equivalent to the 0.2% of alkylphenol), heat and melt, and drive out the hollow gas of the kettle with nitrogen. Raise the temperature to about 180 ℃, start to pass ethylene oxide, and maintain the reaction pressure at 0.3 MPa. When the amount of ethylene oxide is 13 mol, the cloud point is measured by sampling, and the cloud point of 1% aqueous solution is 70~80 ℃, and the reaction is completed. The feed liquid is driven into the neutralization kettle, neutralized with glacial acetic acid, and then decolorized with activated carbon. Filtration, discharge packaging is the finished product.
