20080214778	Method For Producing Polyether Alcohols - 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.	09-04-2008
20090292147	PROCESS FOR THE CONTINUOUS PRODUCTION OF POLYETHER ALCOHOLS - The invention relates to a process for the continuous preparation of polyether alcohols by reacting H-functional initiators with alkylene oxides using basic catalysts, wherein at least one initiator is metered with at least one alkylene oxide continuously into a back-mixing reactor and the reaction product is removed continuously from the back-mixing reactor.	11-26-2009
