Abstract
A method for the production of hulupones by oxidizing lupulones with oxygen in the presence of a catalyst in a polar alkaline medium. The catalysts used include noble metals, oxides of transition metals and particularly oxide metals of Groups IB and VII B, and bismuth oxide on a carrier of kieselguhr, activated carbon, calcium phosphate, magnesium oxide, dolomite, fired clay and strongly acid cation exchangers.
