Method for producing polyether from which metal compounds have been removed |
| abstract |
(57) [Summary] [PROBLEMS] To remove a metal compound from a crude polyether, Provided is a method for producing a polyether, which is performed by a general method that can be achieved in a short time in a simple process. In a purification of a crude polyether containing at least a metal compound derived from a double metal cyanide complex compound catalyst as an impurity, a chelating agent dissolved in water is added to the crude polyether, and the mixture is stirred. And a method for producing a polyether. |
