The invention proposes a method for producing polyether polyols by converting the following reagents a) one or more alkylene oxides and, optionally, carbon dioxide, as well as b) One or more H-functional starting materials in the presence of a catalyst, having several micro-structured layers, A and B, arranged parallel to each other in a reaction unit so that each layer exhibits a multiplicity of channels arranged parallel to each other, forming a continuous flow path from one side of the plate to the side opposite of said plate, characterized in that, a distribution device is proposed at the end of layer A for the channels of said layer to supply the reagents as well as the catalyst, and a collection device is proposed in the other end of said layer for the reaction mixture. |
