Hydrogenation of organic compounds e.g. aromatic amines or phenols, by using hydrogen in presence of catalyst comprising ruthenium on amorphous silicon dioxide based carrier

摘要

Hydrogenation of organic compound(s) (I) comprises contacting (I) with a gas containing hydrogen in the presence of a catalyst (A) containing ruthenium, obtained by treating an amorphous silicon dioxide-based carrier material at least once with a halogen-free aqueous solution of a low molecular ruthenium compound and drying and immediately reducing the obtained solid with hydrogen. Hydrogenation of organic compound(s) (I) comprises contacting (I) with a gas containing hydrogen in the presence of a catalyst (A) containing ruthenium and optionally other Group I, VII or VIII transition metal(s), obtained by treating an amorphous silicon dioxide-based carrier material at least once with a halogen-free aqueous solution of a low molecular ruthenium compound and drying at less than 200 deg C and immediately reducing the obtained solid with hydrogen at 100-350 deg C.
