Method for alkoxidizing polyether polyols |
| abstract |
(57) [Problem] To provide a method for efficiently alkoxide-forming hydroxyl groups of polyether polyols without complicated operations. SOLUTION: In the method of reacting a polyether polyol with an alkali metal alkoxide to alkoxide the hydroxyl terminal of the polyether polyol, the method has a vacuum devolatilization facility, and a stirring shaft is installed from outside the tank. A method for alkoxidizing polyether polyols, comprising using a reaction vessel having a stirring blade having a flat blade on a shaft. |
