    • The invention relates to a method for catalytically hydrating an organic compound, especially an unstable organic compound, in the presence of a supported catalyst that is provided with a coating that contains ruthenium as the active metal and a total of 0.01 to 30 % by weight of active metals. The aim of the invention is to increase stereoselectivity and catalyst service life. To this end, a supported catalyst is used whose oxide-, carbide-, nitride- or silicate-containing support material, prior to being charged with at least one active metal, has a BET(N2) surface of less than 10 m /g, preferably 0.1 to 5 m /g, with the exception of diatomaceous earth with a BET(N2) surface of greater 2 m /g, and whose ruthenium content constitutes at least 50 % by weight, preferably at least 99 % by weight, of the active metals. The invention further relates to the aforementioned supported catalysts. The method and catalysts according to the invention are especially suitable for hydrating polyfunctional compounds such as hydroxycarbonyl compounds and aromatic amines.
    • 本发明涉及一种用于有机化合物的催化氢化,特别是在含有钌作为活性金属和共活性金属涂层的0.01至30重量%的负载型催化剂的存在下不稳定有机化合物的方法。 根据本发明,可与至少一种活性金属装载之前,使用负载的催化剂,该氧化物carbidisches,氮化的或硅酸盐载体材料时,具有BET的小于10μm<2> /克(N 2)的表面区域中获得更高的立体选择性和更高的催化剂寿命 ,特别优选为0.1〜5μm的<2> / g和具有BET硅藻土(N2)表面积大于2m <2> /克被排除,并且其钌中的至少50重量%含量,优选至少99 %的.-%的活性金属。 本发明还涉及上文所述的负载型催化剂。 具体地说,该方法和用于多官能化合物,如羟基羰基化合物和芳香胺的氢化的催化剂。
