Abstract: The invention provides a process for continuously preparing polyether alcohols using DMC catalysts, which comprises, in a first step, in a continuous reactor, adding alkylene oxides onto H-functional starter substances and transferring the output of this reactor to a second step in a reactor which is divided by closed trays into mutually separate sections, known as compartments, which are connected to one another by external pipelines, in which the output of the reactor from the first step of the reaction passes through the compartments in succession.

Abstract: Procedimiento para la obtención en continuo de poliéteralcoholes por medio del empleo de catalizadores DMC, caracterizado porque se adicionan óxidos de alquileno sobre substancias de iniciación H-funcionales en una primera etapa, en un reactor que trabaja en continuo, y la descarga de este reactor se envía, en una segunda etapa, a un reactor, que está subdividido en secciones, denominadas compartimentos, separadas entre sí por medio de fondos cerrados y porque están conectadas entre sí tuberías externas, recorriendo sucesivamente los compartimentos la descarga del reactor de la primera etapa de la reacción, y porque no se dosifica óxido de alquileno en los compartimentos del reactor subdividido.
