| abstract |
The invention relates to Cu-Al-Mn catalyst moldings in extruded form, and to a process for their preparation. The shaped catalyst body is suitable for the hydrogenation of organic compounds which contain a carbonyl function, in particular for the hydrogenation of aldehydes, ketones and of carboxylic acids or their esters. The catalyst molding is very particularly suitable for the hydrogenation of fatty acids or their esters, such as fatty acid methyl esters, to the corresponding alcohols and dicarboxylic anhydrides, such as maleic anhydride (MSA), or esters of diacids to di-alcohols, such as butanediol. |
