put 1 mol C8 ~ 9 alkylphenol into the reaction kettle, add solid alkali as catalyst, add the amount of solid alkali equivalent to the 0.2% of alkylphenol, heat and melt. The air in the kettle was replaced with nitrogen, and after the air was driven clean, ethylene oxide was introduced. The reaction temperature was controlled at 180~190 ℃ and the pressure was controlled at 0.3 MPa. When the intake reaches 18 mol, the reaction continues for 1 h. Then the feed liquid is pumped into the neutralization kettle, neutralized with glacial acetic acid to a pH value of 5~7, and then decolorized with activated carbon. After filtration, the finished product is packaged.
