Noble metal, particularly ruthenium, Raney catalysts which can hydrogenate (1) aromaticity-exhibiting ring portions of organic compounds, (2) carboxylic acids and their ester portions (carbonyl ester groups), (3) ring portions and carboxylic acid or their ester groups in compounds having such ring portions and carboxylic acid or their ester portions, and (4) ring portions and nitrile groups of aromatic nitrile compounds and methods for the preparation of corresponding hydrogenated compounds. The methods allow preparation of hydrogenated compounds having hydrogenated aromatic ring portions, hydrogenated carbonyl ester groups, hydrogenated aromatic ring and carbonyl ester groups, or hydrogenated aromatic rings and nitrile groups under milder hydrogen pressure and temperature conditions than the conventional catalysts.
贵金属,特别是钌,雷尼催化剂,可氢化(1)有机化合物的芳香环部分,(2)羧酸及其酯部分(羰基酯基),(3)具有此类环部分和羧酸或其酯部分的化合物中的环部分和羧酸或其酯基,以及(4)芳香腈化合物的环部分和腈基,以及制备相应氢化化合物的方法。与传统催化剂相比,这些方法可在较温和的氢压和温度条件下制备具有氢化芳环部分、氢化羰基酯基、氢化芳环和羰基酯基或氢化芳环和腈基的氢化化合物。
