put 1 mol of castor oil into the reaction kettle, and then add the catalyst amount of sodium hydroxide aqueous solution. Temperature is raised, vacuumized and dehydrated at 100~120 ℃, then the air in the kettle is replaced with nitrogen, the air in the kettle is driven by air, the pressure is continuously reduced, ethylene oxide is introduced at 140 ℃ for condensation reaction, the reaction temperature is maintained at 140~160 ℃, the vacuum degree is 0.2~0.3 MPa, and the reaction is stopped after passing to a ratio of 10 mol. After cooling, the feed liquid is injected into the neutralization kettle and neutralized with glacial acetic acid until the acid value is 0.4~0.5, then decolorized with appropriate amount of hydrogen peroxide, finally dehydrated for 5 hours, and the finished product is obtained by cooling and discharging.
