Abstract: A process for preparation of polyetherols includes reaction of at least one alkylene oxide with at least one starter compound in the presence of a catalyst which is a multimetal oxide compound. A process for preparation of polyetherols includes reaction of at least one alkylene oxide with at least one starter compound in the presence of a catalyst, i.e. a multimetal oxide compound of formula (I). M1p(M2qOn(OH)2(3-n))x (I) M1 = at least 1 element from the groups IA, IIA, IIIA, IVA, VA, IB, IIB, IIIB, IVB, VB, VIB, VIIB and/or VIIIB; M2 = at least one element from groups IVA, VA and/or VIA, n = 2 or 3, p = 0 or fractional or whole number greater than 0, q = fractional or whole number greater than 0, x = 1-20 fractional or whole number. An Independent claim is included for a polyetherol obtained as above.

Abstract: The invention relates to a method for increasing the catalytic activity of multi-metal cyanide compounds for use as catalysts in the addition of alkyl oxides to H-function starting substances. Said method is characterised in that the multi-metal cyanide compounds are subjected to a deagglomeration before their mixing with the H-function starting substances.

Abstract: A method for making polyether-alcohols using DMC catalysts involves (1) reacting an H-functional starter with propylene oxide (PO) or a mixture of PO and ethylene oxide (EO) and then (2) transferring the mixture to a tubular reactor with at least 2 feed points (FP) for PO/EO mixtures constituted so that the mixtures added in stages 1 and 2 have different PO/EO ratios, there are different PO/EO ratios at different FPs and the mixture added in stage 2 (at least from the last FP) contains at least 40 wt% EO.
