Embodiment 1
[0027] (1) Add 1593 parts of 3-phenyl-2-propen-1-ol and 9 parts of potassium hydride into the stainless steel high-pressure reactor. The stainless steel reactor is equipped with a thermometer, a stirrer and a nitrogen inlet pipe; start the external circulation of nitrogen Take out the air in the reactor under stirring, and raise the temperature to 110±5°C under nitrogen atmosphere, maintain 110°C, add 5117 parts of ethylene oxide under the pressure of 180KPa, react for 4 hours, and then keep it at 110-120°C for 3 hours. Ethylene oxide reacts to completion to obtain a phenylallyl polyether (designated BE-10) in which the average addition of ethylene oxide to 3-phenyl-2-propen-1-ol The molar ratio is 10:1; then, the reactor is cooled to 40°C, and 5100 parts of BE-10 are taken out;
[0028] (2) After taking out 5100 parts of BE-10, continue to heat the reactor to 110°C under a nitrogen atmosphere, maintain 110°C, add 6302 parts of ethylene oxide under a pressure of 180KPa to reac...
Embodiment 2
[0030] (1) Add 1593 parts of 2-phenyl allyl alcohol and 9 parts of potassium hydride into the stainless steel high-pressure reactor. The stainless steel reactor is equipped with a thermometer, a stirrer and a nitrogen inlet pipe; start the external circulation to carry out the reaction under nitrogen stirring Air in the container, and raise the temperature to 110±5°C under a nitrogen atmosphere, maintain 110°C, add 2600 parts of ethylene oxide at 150KPa, react for 4 hours, and then keep warm at 110-120°C for 3 hours to complete the reaction of ethylene oxide. A phenylallyl polyether (named ME-5) was thus obtained in which an average of 5 moles of ethylene oxide were added to 3-phenyl-2-propen-1-ol; then, the reactor was cooled to 30°C, take out 2200 copies of ME-5;
[0031] (2) After taking out 2200 parts of ME-5, continue to heat the reactor to 110°C under nitrogen atmosphere, maintain 110°C, add 4907 parts of ethylene oxide at 150KPa to react for 6 hours, and keep warm at 11...
Embodiment 3
[0033] (1) Add 1593 parts of 3-phenyl-2-propen-1-ol and 9 parts of potassium hydride into the stainless steel high-pressure reactor. The stainless steel reactor is equipped with a thermometer, a stirrer and a nitrogen inlet pipe; start the external circulation of nitrogen Take out the air in the reactor under stirring, and raise the temperature to 110±5°C in a nitrogen atmosphere, maintain 110°C, add 6747 parts of propylene oxide at 100KPa, react for 4 hours, and then keep warm at 110-120°C for 3 hours to make the propylene oxide The reaction was complete, thereby obtaining a phenylallyl polyether (named BP-10), in which an average of 10 moles of propylene oxide was added to 3-phenyl-2-propen-1-ol; then, the reaction The temperature of the device was lowered to below 50°C, and 6724 copies of BP-10 were taken out;
[0034] (2) After taking out 6724 parts of BP-10, continue to heat the reactor to 110°C under nitrogen atmosphere, maintain 110°C, add 8310 parts of propylene oxide ...
