摘要：
Novel ruthenium catalysts additionally contain carbonates, hydroxides and/or hydrated oxides of cerium and manganese or of manganese and/or dehydration products thereof. They can optionally be present on a support material and can be prepared by converting soluble compounds of ruthenium, cerium and manganese by treatment with alkaline compounds into insoluble compounds and optionally further treating these. Such catalysts are particularly suitable for the preparation of cycloaliphatic polyamines by hydrogenation of corresponding aromatic amines.
