put 1 mol C8 ~ 9 alkylphenol into the reaction kettle, add 50% lye (equivalent to 0.2% of alkylphenol mass), dissolve and dehydrate by vacuum, gradually raise the temperature to 120~140 ℃, and remove the water. Dry nitrogen is introduced to replace the air in the kettle, and the temperature is raised to about 160 ℃ after the air supplement is exhausted. Ethylene oxide is introduced to carry out condensation reaction. During the reaction, the kettle pressure is maintained at about 0.2 MPa. The amount of ethylene oxide is 8 mol. After the injection is completed, the cloud point of 1% aqueous solution is measured. The cloud point of 1% aqueous solution is 30~35 ℃ as the end point. Then the feed liquid is pumped into the neutralization kettle, acetic acid is added for neutralization, pH value is adjusted to 5~7, and activated carbon is added for decolorization. After filtration, the finished product is packaged.
