METHOD FOR PRODUCING POLYETHER ALCOHOLS

The invention relates to a method for producing polyether alcohols by the catalytic addition of alkene oxides to a parent substance containing water-soluble, H-functional parent substances that are solid at ambient temperature and alcohols and water that are liquid at the reaction temperature, using alkali hydroxide and/or alkaline-earth hydroxides as catalysts. The method is characterised in that the quantity of water is between 1.0 and 6.0 wt. %, in relation to the weight of the parent substance mixture, the latter containing no aminic constituents. La invencion se relaciona con un metodo para producir alcoholes de polieter mediante al adicion catalitica de oxidos de alqueno a una substancia original que contiene substancias originales H-funcionales, solubles en agua que son solidas a temperatura ambiente y alcoholes y agua que son liquidos a la temperatura de reaccion, utilizando hidroxido de alquilo y/o hidroxidos alcalino terreos como catalizadores. El metodo se caracteriza en que la cantidad de agua es entre 1.0 a 6.0% en peso, con relacion al peso de la mezcla de substancia original, la ultima no conteniendo constituyentes aminicos.
