Abstract: The invention relates to a method for reacting epoxides with a starter-compound in the presence of a double metallocyanide-compound as a catalyst with reduced induction times. The activation of the double metallocyanide-compound occurs by adding the epoxides to a mixture made from double metallocyanide-compounds and starter compounds at an inner pressure of the reactor of less than 1 bar. The invention also relates to a polyether which can be obtained by means of said method.

Abstract: The invention relates to a method for producing polyether alcohols, comprising the following steps: a) reacting a low-molecular alcohol with alkylene oxide in the presence of a basic catalyst in order to form an alkylene oxide addition product having a molecular weight ranging from 200 to 900 g/mol; b) separating the basic catalyst from the product obtained in step a), and; c) reacting the product obtained in step b) with another alkylene oxide in order to produce the desired final product while using at least one DMC catalyst. The inventive method is characterized in that sodium hydroxide is used as the basic catalyst in step a).

Abstract: The invention concerns a method for producing at least one alkoxylated product, consisting in contacting an alkylene oxide mixture containing at least ethylene oxide with at least one initiator compound in the presence of at least one double metal cyanide compound, the sum of the inert gas partial pressure and of the ethylene oxide partial pressure ranging between 1.5 bar and 6.0 bar during the induction phase. The invention also concerns the alkoxylated products obtained by said method and the use of such products as emulsifiers, foam adjusting and wetting agents for hard surfaces.

Abstract: The present invention relates to a process for the alkoxylation of organic compounds comprising the reaction of at least one organic compound with at least onealkoxylating agent in the presence of a catalyst system, wherein a polyetheralcohol is obtained. The catalyst system comprises a metallo organic framework mate-rial comprising pores and at least one metal ion and at least one at least bidentate organic compound, which is coordinately bounded to said metal ion. Furthermore it relates to polyurethanes or polyurethane foams, which are obtainable by using a prepared polyether alcohol as a starting material.
