Method for hydrogenating organic compounds by means of RU/SIO2 catalysts

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.
