Abstract (en)
[origin: WO2007135154A1] The invention proposes a method for producing polyether polyols by converting the following reactants: a) one or several alkylene oxides and, optionally, carbon dioxide, as well as b) one or several H-functional starting materials in the presence of a catalyst, having several micro-structured layers, A and B, arranged parallel to one other in a reaction unit such that each layer displays a multiplicity of channels arranged parallel to one another, which form a continuous flow path from one side of the plate to the opposite side of said plate, characterized by the fact that, a distribution device is proposed at the end of layer A for the channels of said layer to supply the reactants as well as the catalyst, and a collection device is proposed at the other end of said layer for the reaction mixture.
