Embodiment 1
[0025] Take 316g of refined pentadecyl (en)-based meta-diphenol and put it into a high-pressure reactor, add 0.632g of 50% potassium hydroxide solution, carry out nitrogen replacement, control the vacuum degree ≥ -0.095MPa, and replace the pressure to 0.15MPa~0.25 MPa; after the nitrogen replacement is completed, the temperature is raised to 110°C to 130°C for dehydration, and after the dehydration is completed, the temperature is raised to 135°C to 160°C, and 440g of ethylene oxide is added to carry out the epoxidation reaction, and the temperature of the addition reaction is controlled at 130°C ~190°C, the pressure is controlled below 0.3MPa, after the addition reaction is completed, the temperature is lowered to 65°C~75°C, and then 0.34g of acetic acid is added to neutralize the pH value to 5.0~8.0 to obtain pentadecyl (enyl) meta Phenol polyoxyethylene ether. Put pentadecyl (en)-based meta-diphenol (cardol) polyoxyethylene ether into the reactor, start stirring, and raise ...
