The
stability and catalytic behaviour of a ruthenium complex with chloride and
tridecylamine as ligands were studied. The hydrogenaation of cyclohexene
carried out in mild conditions, both in homogeneous and heterogeneous
conditions, was used as a test reaction. FTIR and XPS results show that the
active species is the complex itself, which is stable under the reaction
conditions. XPS determination shows that the ruthenium complex is
tetra-coordinated, suggesting that its formula is [RuCl2(NH2(CH2)12CH3)2].
This ruthenium complex supported on g-Al2O3
is more active and sulfur-resistant thaan the same complex unsupported and even
more than a nickel complex with the above mentioned ligands. The Ru complex,
supported or not, is also more active and sulfur-resistant than the
conventional Ru/g-Al2O3
catalyst evaluated in the same operational conditions.
