Abstract: (Meth)acrylates of polyhydric alcohols are prepared by reacting (meth)acrylic acid and the corresponding polyhydric alcohol in the presence of at least one acidic catalyst and, if required, at least one polymerization inhibitor and in the presence or absence of a solvent, by a process in which the polyhydric alcohol used contains less than 500 ppm of bound formaldehyde.

Abstract: Trimethylol propane is isolated from a reaction mixture, obtained by reaction of n-butyraldehyde with formaldehyde in the presence of a base and optional hydrogenation of the mixture obtained. The mixture is distilled using a partition column or a distillation column with a pre-column or a distillation column with a post-column. The method is characterised by a low investment and energy cost and the reduced formation of high-boiling by-products.

Abstract: The invention relates to a method for removing acetals containing formaldehy de from polyvalent alcohols, especially trimethylolpropane. The inventive metho d is characterised in that the polyvalent alcohol is liberated of low-boiling constituents after it has been produced by distillation, is then subjected t o tempering and is repurified, preferably by means of distillation.

Abstract: A method for removing trialkyl ammonium formate from a methylol alkanes obtained by condensation of formaldehyde with a higher aldehyde. The invention is characterized in that trialkyl ammonium formate is decomposed at a high temperature using catalysts containing at least one metal from groups 8-12 of the classification of elements in the presence of gas containing hydrogen. The method makes it possible to separate trialkyl ammonium formate according to the organic Cannizzaro method and according to the hydrogenation method.

Abstract: Removal of trialkylammonium formates (TAAF) from methylolalkanes obtained by condensation of formaldehyde with higher aldehydes involves decomposing the TAAF at elevated temperature on a titanium dioxide- supported ruthenium-containing catalyst in presence of a hydrogen-containing gas. An independent claim is also included for such a catalyst in which commercially-available titanium dioxide is treated before or after shaping to form the support with 0.1-30 wt.% of an acid in which the TiO 2 is difficultly soluble.

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: 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.
