Abstract: Colloidal palladium for hydrogenating olefins, acetylene, dienes and (un)saturated nitriles consists of palladium clusters having an average particle size of 0.2-2.0 nm. At least 80% of the palladium clusters have a particle diameter which deviates not more than 0.2 nm from the average particle diameter. The clusters have protective ligands on the surface. Independent claims are also included for: (1) production of a palladium colloidal solution by reacting a palladium salt with a reductant made of 4-30 C alcohol, and a protective ligand of phosphane and/or aromatic nitrogen compound at 0-300o C; (2) production of colloidal palladium comprising forming the above palladium colloidal solution, precipitating the colloidal palladium by adding a hydrocarbon solvent, removing the colloidal palladium, and drying; and (3) production of a palladium-containing heterogeneous catalyst by forming the palladium solution as above, impregnating a carrier selected from alumina, silicon dioxide, zirconium dioxide, titanium dioxide, carbon, zeolite and silicate.
