Investigation of the hydrogenation of ?-, ?-, and ?-acetylenic hydrocarbons in their binary mixtures over a skeletal nickel catalyst

Abstract

1. In binary mixtures of normal α-acetylenic hydrocarbons (C5-C7), β-acetylenic hydrocarbons (C5-C6), and of β- and γ-acetylenic hydrocarbons (C5-C6), over a skeletal nickel catalyst the components of the mixture are hydrogenated simultaneously at identical rates. 2. In the first stage of the hydrogenation of binary mixtures of α- and β- and of α- and γ-acetylenic hydrocarbons, the α-acetylenic hydrocarbons are hydrogenated preferentially. 3. The C5-C7 acetylenic hydrocarbons studied and the olefins formed from them are hydrogenated in the following order, characterizing their relative adsorbabilities by a nickel catalyst: α-acetylenic hydrocarbons, β- and γ-acetylenic hydrocarbons, α-olefins, β- and γ-olefins.
