Abstract: The invention relates to a method for catalytically hydrating a poly- or monomethylol alkanal of the general formula (I), wherein R is the same or different and may represent a substituted or unsubstituted aliphatic hydrocarbon with 6 to 22 carbon atoms, an aryl or arylalkyl group with 6 to 22 carbon atoms or a methylol group, in the presence of a copper-containing catalyst. The inventive method is characterized in that the poly- or monomethylol alkanal containing batch to be hydrated has a total content of up to 5 ppm of metal ions of the groups 3 to 14 of the periodic system.

Abstract: A process for the purification of polymethylolalkanoic acids or monomethylolalkanoic acids comprises oxidation of the corresponding alkanal using an aqueous solution of hydrogen peroxide, crystallization followed by a solid-liquid separation whereby following the solid-liquid separation the mother liquor associated with the resulting crystallizate is diluted with a solvent or solvent mixture. A process for the purification of polymethylolalkanoic acids or monomethylolalkanoic acids of formula (1) comprises oxidation of the corresponding alkanal of formula (2) using an aqueous solution of hydrogen peroxide, crystallization followed by a solid-liquid separation whereby following the solid-liquid separation the mother liquor (M1), associated with the resulting crystallizate (FK1) is diluted with a solvent or solvent mixture (L1) such that the dilute mother liquor (M1) is separated to yield the crystallizate (FK2).

Abstract: The invention relates to a method for producing poly- or monomethylol alkanoic acids of general formula (I), R being the same or different and meaning a substituted or unsubstituted aliphatic hydrocarbon with 1 to 22 C-atoms or a methylol group; from the corresponding poly- or monomethylol alkanals of general formula (II), R having the meaning above, by oxidation with hydrogen peroxide. The poly- or monomethylol alkanal of general formula (II) used in the reaction has an overall content of metal ions of groups 3 to 14 of the periodic table of up to 5 ppm. The method is used especially for producing dimethylol allkanoic acids from the corresponding dimethylol alkanals, especially for producing dimethylol butanal or dimethylol propanal.
