In a process for hydrogenating at least one organic compound, the organic compound or compounds is/are brought into contact with a hydrogen-containing gas in the presence of a catalyst which comprises, as active metal, ruthenium either alone or together with at least one further metal of transition group I, VII or VIII of the Periodic Table applied to a support material based on amorphons silicon dioxide and is obtainable by:
i) a single or multiple treatment of a support material based on amorphous silicon dioxide with a halogen-free aqueous solution of a low molecular weight ruthenium compound and subsequent drying of the treated support material at below 200° C.,
ii) reduction of the solid obtained in i) by means of hydrogen at from 100 to 350° C.,
with step ii) being carried out directly after step i).
在至少一种有机化合物氢化的过程中,有机化合物或化合物被带入含氢气体中,在催化剂的存在下,该催化剂包括作为活性金属的钌单独或与周期表的I,VII或VIII族过渡金属中的至少一种进一步金属一起应用于基于非晶态二氧化硅的支撑材料,并且可以通过以下方式获得:i)用不含卤素的低分子量钌化合物的水溶液对基于非晶态二氧化硅的支撑材料进行单次或多次处理,并在低于200°C的条件下干燥处理所处理的支撑材料,ii)通过在100°C至350°C的温度下用氢还原i)中得到的固体,其中步骤ii)直接在步骤i)之后进行。
