Abstract: In a process for preparing polyether alcohols by catalytic addition of at least two alkylene oxides onto H-functional initiator substances, at least one multimetal cyanide compound is used as catalyst and the addition of the alkylene oxides onto the initiator substance includes incorporation of at least one oxyalkylene block during whose formation at least two alkylene oxides are metered in together and the ratio of the alkylene oxides to one another in the mixture is changed during the joint introduction.

Abstract: A process for the production of flexible polyurethane foam comprises reacting: (a) optionally modified polyisocyanates with: (b) compounds with reactive hydrogens, and (c) optionally chain extenders and/or crosslinkers, in presence of: (d) blowing agents, (e) catalysts, (f) fire retardants, and optionally: (g) other additives etc. At least 10 wt% of the compounds used in this process comprises polyether-polyols obtained by base-catalysed reaction of lower alkylene oxides with hydroxy-functional starters and subjected, during or after alkylene oxides-addition and with a water content of not more than 0.1 wt.%, to distillation at temperatures above 49 degrees C.

Abstract: The invention relates to a method for producing polyether alcohols by the catalytic reaction of H functional compounds with alkylene oxides, whereby at least one multi-metal cyanide compound is used as the catalyst. The method is characterised in that the total content of alkaline and acidic impurities contained in the starting material and the alkylene oxides, which reduce the activity of the catalyst, is less than 100 ppm.

Abstract: A process for preparing two-metal cyanide catalysts, comprises combining an aqueous solution of a metal salt of the formula M1m(X)n, where M1 is a metal ion selected from the group consisting of Zn(II), Fe(II), Co(III), Ni(II), Mn(II), Co(II), Sn(II), Pb(II), Fe(III), Mo(IV), Mo(VI), Al(III), V(IV), V(V), Sr(II), W(IV), W(VI), Cr(II), Cr(III), X is an anion selected from the group consisting of halide, hydroxide, sulfate, carbonate, cyanate, thiocyanate, isocyanate, carboxylate, oxalate or nitrate and m and n are derived from the valences of M1 and X, with an aqueous solution of a cyanometalic acid of the formula HaM2(CN)b(A)c, where M2 is a metal ion selected from the group consisting of Fe(II), Fe(III), Co(III), Cr(III), Mn(II), Mn(III), Rh(III), Ru(II), V(IV), V(V), Co(II) and Cr(II), where M2 can be identical to or different from M1. A is an anion selected from the group consisting of halide, hydroxide, sulfate, carbonate, cyanide, thiocyanate, isocyanate, cyanate, carboxylate, oxalate or nitrate, where A can be identical to or different from X, a, b and c are integers and are selected such that the cyanide compound is electrically neutral, where one or both aqueous solutions may comprise at least one water-miscible organic ligand selected from the group consisting of alcohols, aldehydes, ketones, ethers, polyethers, esters, ureas, amides, nitriles or sulfides, if desired, combining the aqueous suspension thus obtained with at least one water-miscible organic ligand selected from the abovementioned group, which ligand may be identical to or different from any previously added ligand, and separating the resulting two-metal cyanide complex from the suspension.

Abstract: Process for preparing polyether polyols having an end block of ethylene oxide by addition of alkylene oxides onto H-functional starter substances, in which A) a polyether polyol precursor is prepared by means of double metal cyanide (DMC) catalysis in a semicontinuous mode of operation in which previously prepared polyether polyol together with the DMC catalyst are placed in a reactor and H-functional starter substance and propylene oxide are added continuously, B) the polyether polyol precursor from stage A) is reacted with propylene oxide or an ethylene oxide/propylene oxide mixture in the presence of the DMC catalyst in a continuously operating reactor to give a polyether polyol intermediate, C) the intermediate from stage B) is mixed with an alkali metal hydroxide as catalyst and D) reacted with ethylene oxide in a continuously operating reactor to give the final product, E) the catalyst is separated off from the final product obtained in stage D).
