Abstract

Pd25Zr75, Pd22Cu10Zr68, and Pd72Cu10Si18 alloy ribbons prepared by the rapid quenching technique, and Pd25Zr75, Pd25Cu10Zr65, Pd80Si20, and Pd72Cu10Si18 alloy powders made by mechanical alloying proved to be amorphous by X-ray diffraction and differential scanning calorimetry. The powder samples after HF treatment have been found to exhibit high selectivity in the semihydrogenation of 1, 3-cyclooctadiene: The pronounced drop in the hydrogen uptake after the complete consumption of the diene allows the selective synthesis of the corresponding monoene.
