Homogeneous hydrogenation of unsaturated organic compounds catalyzed by rhodium complexes containing trioctylamine as a ligand
- Topchiev Institute of Petrochemical Synthesis, Moscow (Russian Federation)
Two new types of toluene-soluble rhodium-complex catalysts for hydrogenation of multiple carbon-carbon bonds are synthesized by the reaction of rhodium salts with trioctylamine. The productivity of these catalysts reaches 26000 moles of substrate per gram-atom of rhodium per hour at 20{degrees}C and at a hydrogen pressure of 0.1 MPa. The promoting effect of molecular oxygen and water on homogeneous rhodium-complex catalysts prepared by direct interaction of rhodium trichloride with trioctylamine is established. A scheme for catalyst activation involving the reversible chemisorption of oxygen by the complex is proposed on the basis of IR-spectroscopic data. The kinetics of hydrogenation of unsaturated hydrocarbons is studied.
