put 1 mol C8 ~ 9 alkylphenol into the reaction kettle, strengthen the alkali (the amount of alkali added is equivalent to the 0.3% of phenol), heat and melt, replace the air in the kettle with nitrogen, and then pass ethylene oxide into the reaction to start the condensation reaction. in the reaction, the reaction temperature is controlled to be about 170 ℃, and the pressure is 0.2~0.3 MPa. When it reaches 12 mol, the cloud point is measured by sampling. If the cloud point of 1% aqueous solution reaches 76 ℃, the reaction ends. The feed liquid is driven into the neutralization kettle, neutralized with glacial acetic acid, and then decolorized with activated carbon. After filtration, the discharge package is the finished product.
