ABSTRACT
This study examined investigation of the catalytic activity of ruthenium carboxylates with triphenylphosphine and tributylphosphine ligands in hydrogenation reaction. The hydrogenation reaction is one of the most important reactions in the ground and fine organic synthesis, in the desulfurization of hydrocarbons and in the production of intermediates. To analyze the conversion ethyl trans-cinnamate the 1H NMR spectroscopy was used. To stabilize the ruthenium complexes were used sterically demanding triphenylphosphine and tributylphosphine and to increase the solubility of organic solvents was specifically synthesized carboxylates with methoxy, methoxyethoxy and metoxydietoxy groups. All used catalysts were tested by the pressure of hydrogen 40-100 bar. Increasing the pressure increases the catalytic conversion according to Le Chatelier’s principle.

Keywords: catalytic activity, ruthenium catalysts, hydrogenation reactions, ruthenium carboxylats, homogeneous catalyses, nanoparticle, homogeneous catalyses.
