  • Patent number: 5600012
    Abstract: Tetrahydro-iso-.alpha.-acids ("THIAA") are prepared directly from iso-.alpha.-acids ("IAA") by hydrogenation. Free IAA are first dissolved in ethanol. The solution is then hydrogenated in the presence of a particular type of noble metal catalyst. Hydrogenation is controlled naturally by the reaction between the catalyst and the IAA so that the IAA will be selectively converted to THIAA without unacceptable perhydrogenation into other forms.
