Abstract: A process is disclosed for the selective hydrogenation of butine-2-diol(1,4) to butene-2-diol(1,4) using a palladium catalyst to which copper and zinc or silver and zinc are added as doping agents. In the preferred embodiment, it has been possible, by optimizing the composition of the catalyst, to improve the activity and selectivity of the catalysts in question while also eliminating the need to handle toxic substances during the catalyst manufacturing process.

Abstract: Process for obtaining aqueous glyoxylic acid solutions which are essentially free from other acids, from aqueous solutions which furthermore contain other acids, by mixing the aqueous solution with an organic nitrogen compound at temperatures of up to 50 DEG C, separating the phases and extracting the glyoxylic acid from the organic phase at a higher temperature using water.
