Abstract
Unsaturated organic compounds, in particular .alpha.-acids and .beta.-acids, are purified prior to hydrogenation by mixing them with an adsorbent capable of adsorbing catalyst poisons, preferably activated carbon, and separating the adsorbent containing the catalyst poisons to recover the thus purified unsaturated organic compounds. A significant reduction in the use of hydrogenation catalyst is realized.
