HOMOGENEOUS AND SUPPORTED CATALYSTS FOR ALPHA-OLEFIN HYDROGENATION BASED ON COMPLEXES OF PLATINUM TETRACHLORIDE WITH ALIPHATIC-AMINES

A new efficient catalyst for cr-olefin hydrogenation that exhibits the catalytic activity without additional treatment with a reducing agent is obtained by the interaction of PtCl4 with tri-n-octylamine. Molecular hydrogen and ethanol are found to promote the catalytically active complex. On the basis of the IR spectroscopic investigation, a likely structure of the synthesized complex is proposed. A highly active heterogenized platinum-containing catalyst for the hydrogenation of terminal double bonds is prepared by supporting a homogeneous system on gamma-Al2O3.
