Abstract
It is shown that the composition of the mixture, obtained on hydrogenating humulone, is determined by the amount of absorbed hydrogen, the pH of the solution and the nature of the catalyst. A maximum tetrahydrohumulone yield of 84% is obtained in methanol solution at pH 5,1 with Pt as catalyst, when 2,35 mole of hydrogen are allowed to react.
