1mol of tridecanoic acid is heated and melted with solid KOH, and 9mol of ethylene oxide is introduced. React at 180~200 ℃ and 0.2~0.3MPa. After passing through ethylene oxide, sample and measure the cloud point. The reaction is completed when the cloud point of the 1% aqueous solution reaches 30-40 ℃. Transfer the material into a neutralization kettle, adjust the pH value to 5.0-6.0 with acetic acid, decolorize with hydrogen peroxide, and cool the discharge to obtain the finished product.
