Abstract: Disclosed is a method for the catalytic hydrogenation of methylol alkanals of general formula (I), where R 1 and R 2 independently represent an additional methylol group or an alkyl group having with 1 to 22 carbon atoms, or an alkyl group with 1 to 22 C atoms, or an aryl group or aralkyl group with 6 to 33 carbon atoms, in the liquid phase on a hydrogenation catalyst. The inventive method is characterized in that a pH value ranging between 6.3 and 7.8 is adjusted in the hydrogenation feed by adding at least one tertiary amine

Abstract: The invention relates to a method for increasing yield in the production of polyvalent alcohols, especially trimethylolpropane, obtained by condensing formaldehyde with a higher aldehyde. According to the inventive method, acid treatment is carried out on a mixture (high-boiling fraction) that is obtained by reprocessing, contains derivatives of said alcohols and has a higher boiling point than the respective alcohol, and the polyvalent alcohol is recovered from the acid-treated high-boiling fraction. The inventive method is characterised in that the water content of the high-boiling fraction amounts to between 20 and 90 wt. % in relation to the entire mixture of the high-boiling fraction and water.

Abstract: Trimethylolpropane is isolated from a reaction mixture which has been obtained by reaction of n-butyraldehyde with formaldehyde in the presence of a base and, if appropriate, hydrogenation of the resulting mixture by distilling the mixture by means of a dividing wall column or a distillation column with a precolumn or a distillation column with an after-column. The process has low capital costs and a low energy consumption and gives reduced formation of high-boiling by-products.

Abstract: Production of substituted pyrrole-2-carboxylic esters comprises reaction of alpha -nitroso- beta -oxoesters with beta -carbonyl compounds, in a hydrogen-containing atmosphere, in the presence of a noble metal-containing catalyst. Production of substituted pyrrole-2-carboxylic esters of formula (I) comprises reaction of alpha -nitroso- beta -oxoesters of formula (II) with beta -carbonyl compounds of formula (III), in a hydrogen-containing atmosphere, in the presence of a noble metal-containing catalyst. R -R = optionally functionalized aliphatic, cycloaliphatic, aromatic, araliphatic or 1-20C heterocycle. Where: (1) R and R can additionally be -CHO, -COOH (both in protected form) or -CN; (2) R can additionally be -OH, with the proviso that R = optionally functionalized aliphatic, cycloaliphatic, aromatic, araliphatic or heterocyclic of 1-20C; and (3) R can additionally be H.
