New heterogeneous ruthenium catalyst comprising amorphous silicon dioxide, useful in the hydrogenation of a carbocyclic aromatic group to the corresponding carbocyclic aliphatic group

摘要

Heterogeneous ruthenium catalyst comprising an amorphous silicon dioxide as substrate (obtained by the impregnation of one or more carrier material with a ruthenium salt solution, followed by drying and reduction; and where the silicon dioxide carrier material exhibits a Brunauer-Emmett and Teller surface (BET surface, according to DIN 66131) of 250-400 m 2>/g, a pore volume (according to DIN 66134) of 0.7-1.1 ml/g and a pore diameter (according to DIN 66134) of 6-12 nm), is new. An independent claim is included for the hydrogenation of a carbocyclic aromatic group to the corresponding carbocyclic aliphatic group comprising using heterogeneous ruthenium catalyst.
