The invention relates to starting compounds which can be used for the preparation of polyurethanes and can be prepared by reaction of hydroxyl-containing oligomers of formaldehyde.

Initial compounds for producing polyurethanes

A method of forming a polyethercarbonate polyol enhances incorporation of COinto the polyethercarbonate polyol. The method provides a catalyst including a multimetal cyanide compound. An H-functional initiator, an alkylene oxide, and COare reacted in the presence of the multimetal cyanide compound in a reactor. The method further provides a CO-philic compound or a CO-philic substituent. The CO-philic compound and substituent enhance incorporation of the COinto the polyethercarbonate polyol and reduce formation of cyclic alkylene carbonates, such as cyclic propylene carbonate, which are undesirable byproducts.

[object Object]

A method of forming a polyethercarbonate polyol enhances incorporation of COinto the polyethercarbonate polyol. The method provides a catalyst including a multimetal cyanide compound. The multimetal cyanide compound has an ordered structure defined by a cationic catalytic center and an anionic backbone with the anionic backbone spatially arranged about the cationic catalytic center. The anionic backbone is modified with a supplemental anionic spacer to affect the spatial arrangement and catalytic activity of the cationic catalytic center. The supplemental anionic spacer is incorporated into the multimetal cyanide compound to establish the general formula, M[M(CN)MX], wherein M, M, and Mare various metal ions and X is the supplemental anionic spacer. An H-functional initiator, an alkylene oxide, and COare reacted in the presence of the modified multimetal cyanide compound to form the polyethercarbonate polyol.

Complex of a multimetal cyanide compound and methods of forming polyethercarbonate polyols

A polyether polyol is formed by a method utilizing a carboxy-modified aluminum-based catalyst. The method includes providing an alkylene oxide, providing an initiator molecule having at least one alkylene oxide reactive hydrogen, and reacting the alkylene oxide with the initiator molecule in the presence of the catalyst. The ideal carboxy-modified aluminum based catalysts used herein are selected from the group of carboxy-modified aluminum phosphate catalysts, carboxy-modified aluminum phosphonate catalysts, and residues or mixtures thereof.

Method of forming polyetherols in the presence of carboxy-modified aluminum-based catalysts

A method for the production of polyetherols is disclosed. The method includes the utilization of aluminum phosphonate catalysts for the formation of the very low unsaturation polyether polyols. The aluminum phosphonate catalyst preferably has a general structure of RPO&#x2014;(OAlR'R&#x2033;), wherein O represents oxygen, P represents pentavalent phosphorous, Al represents aluminum, R comprises a hydrogen, a methyl group, an alkyl group, or an aryl group, and R&#x2032; and R&#x2033; independently comprise a halide, an alkyl group, an alkoxy group, an aryl group, or an aryloxy group. Polyols produced according to the disclosed procedure have properties identical to or more beneficial than those produced utilizing the typical base catalysts.

Production of polyetherols using aluminum phosphonate catalysts

A carboxy-modified aluminum-based catalyst composition is of the general formula P(O)(OAlR'R&#x2033;)or RP(O)(OAlR&#x2032;R&#x2033;)wherein O represents oxygen, P represents pentavalent phosphorous, Al represents aluminum, R comprises hydrogen, an alkyl group, or an aryl group, and R&#x2032; and R&#x2033; independently comprise a halide, an alkyl group, a haloalkyl group, an alkoxy group, an aryl group, an aryloxy group, or a carboxy group, so long as at least one of R&#x2032; and R&#x2033; is a carboxy group. The carboxy-modified aluminum-based catalyst composition is, generally, the reaction product of phosphoric acid or a pentavalent phosphonic acid, a tri-substituted aluminum compound, and a carboxylic acid.

An improved method for synthesizing a double metal cyanide (DMC) catalyst combines and sonicates aqueous and non-aqueous solutions of a first metal salt, such as Zn(OAc), of a second metal salt, such as CoCl, and of an alkali metal cyanide, such as NaCN, to synthesize the DMC catalyst, Zn[Co(CN)]. An improved method of producing a polyether polyol uses the DMC catalyst to produce the polyol.

An improved method for synthesizing a double metal cyanide (DMC) catalyst includes combining a non-aqueous solution of a first metal salt, such as ZnBr, with a non-aqueous solution of a second metal salt, such as CoBr, and with a non-aqueous solution of an alkali metal cyanide, such as NaCN, in a single step to synthesize the DMC catalyst, Zn[Co(CN)].

Synthesis of double metal cyanides with non-aqueous solutions

A method of removing and reclaiming a double metal cyanide (DMC) catalyst from a polyol is disclosed. A polymeric acid that is soluble in the polyol is introduced into the polyol during or after the polymerization reaction. The polymeric acid reacts with the double metal cyanide catalyst thereby causing the double metal cyanide catalyst and the polymeric acid to form an agglomeration in the polyol. The agglomeration is easily separated from the polyol via filtration, for example. The recovered agglomerated DMC catalyst can then be reconstituted using an acid solution.

A method of forming a polyol includes the steps of reacting an initiator with an alkylene oxide, and optionally carbon dioxide, in the presence of a double metal cyanide catalyst and a sterically hindered chain transfer agent capable of protonating the growing polyol polymer. The presence of the chain transfer agent reduces the polydispersity of the resultant polyol.
