TLDR: In this paper, the results of the semihydrogenation at atmospheric pressure of acetylene over a Pd catalyst known as Pdc prepared from the reaction of palladium acetate, sodium hydride, and t-amyl alcohol are reported.

Abstract: Results of the semihydrogenation at atmospheric pressure of acetylene over a Pd catalyst known as Pdc prepared from the reaction of palladium acetate, sodium hydride, and t-amyl alcohol are reported. The Pd catalyst preparation is analogous to that of the Ni catalyst known as Nic previously reported by the authors. Different modes of preparation of the catalysts gave different selectivity for hydrogenation; however, the same mode of preparation for different batches of catalyst resulted in consistently high selectivity of hydrogenation (98.5 +/- 0.3%). The effect of temperature on hydrogenation of simple acetylenes to (Z)-alkenes was also studied.
