Abstract:
The present invention relates to a process for preparing diols by hydrogenating a mixture comprising carboxylic acid, carboxylic anhydrides and/or carboxylic esters/lactones by means of a cobalt-comprising catalyst, wherein alkali metal and/or alkaline earth metal ions are added to the hydrogenation feed, excluding alkali metal and/or alkaline earth metal ions of mineral acids.
