HOMOGENEOUS CATALYSTS FOR THE HYDROGENATION OF UNSATURATED-HYDROCARBONS BASED ON COMPLEXES OF PLATINUM TETRAACETATE WITH ALIPHATIC-AMINES

New platinum-containing catalysts, efficient for the complete hydrogen ation of unsaturated hydrocarbons based on complexes of platinum tetra acetate and aliphatic amines, are developed. The kinetics of hydrogena tion are studied. Using the method of fractional inhibition by carbon monoxide, it is shown that the possible fraction of the metal involved in the formation of active centers makes up 20% of the amount of the platinum introduced. The complex of platinum tetraacetate with tri-n-n onylamine is found to exhibit a high stability to a prolonged exposure to oxygen and water. On the basis of the IR-spectroscopic investigati on of the complexes synthesized, their probable structures are propose d. The data obtained suggest that the hydride forms of platinum are re sponsible for the catalytic activity.
