Method for producing polyether alcohols

The invention relates to a process for preparing DMC catalysts by reacting cyanometalate compounds, preferably cyanometalate salts, in particular alkali metal or alkaline earth metal salts, with metal salts, wherein the reaction is carried out in the presence of a Br&#xf6;nsted acid.

Method for producing an DMC catalyst

The invention relates to a process for producing flexible polyurethane foams, in particular molded flexible polyurethane foams, by reacting a) polyisocyanates with b) compounds having at least two hydrogen atoms which are reactive toward isocyanate groups, wherein at least one polyether alcohol bi) which has been prepared by means of a DMC catalyst and has a hydroxyl number in the range from 15 to 35 mg KOH/g, and ethylene oxide content in the range from 5 to 18% by weight, based on the total weight of the polyether alcohol and an end block of ethylene oxide and propylene oxide having an ethylene oxide content of from 25 to 75% by weight, based on the amount of alkylene oxide in the end block, is used as compound b) having at least two hydrogen atoms which are reactive toward isocyanate groups.

Method for producing polyurethane-soft foam materials

The invention provides a process for preparing polyether alcohols by adding alkylene oxides onto H-functional starter substances using DMC catalysts, which comprises, in a first step, adding propylene oxide or a mixture of propylene oxide and ethylene oxide onto H-functional starter substances and, in a second step, transferring the product thus formed into a tubular reactor in which mixtures of ethylene oxide and propylene oxide are metered in at least two metering points, the proportions of ethylene oxide and propylene oxide in the mixtures metered in in the first and in the second step being different, the proportions of ethylene oxide and propylene oxide in the mixtures metered in at least two metering points in the second step being different, and the mixture metered in in the second step, at least at the last metering point, comprising at least 40% by weight of ethylene oxide.

Method for production of polyether alcohols

The invention relates to polyether alcohols, to a process for preparing polyether alcohols by reacting alkylene oxides in the presence of a double metal cyanide (DMC) catalyst with at least one saturated OH component which may, if appropriate, have previously been reacted with an alkylene oxide, wherein an antioxidant is added before or during the reaction, and also to the further processing of the polyether alcohols to form polyurethanes.

Polyether alcohols and method for the production of polyether alcohols for polyurethane synthesis

The present invention relates to a process for preparing a polyetherol which comprises reacting at least one alkylene oxide with at least one starter compound in the presence of a catalyst of the formula I:M[MO(OH)],&#x2003;&#x2003;(I)and to the polyetherols prepared by such a process and to their use for the synthesis of polyurethanes, as fuel additive or as surfactant.
